Add recursive isEven() test

* Fix to allow variable shadowing inside functions

* Implement closures

* Fix KCL test code to not reference future tag definition

* Remove tag declarator from function parameters

This is an example where the scoping change revealed a subtle issue
with TagDeclarators.  You cannot bind a new tag using a function
parameter.

The issue is that evaluating a TagDeclarator like $foo binds an
identifier to its corresponding TagIdentifier, but returns the
TagDeclarator.  If you have a TagDeclarator passed in as a parameter
to a function, you can never get its corresponding TagIdentifier.

This seems like a case where TagDeclarator evaluation needs to be
revisited, especially now that we have scoped tags.

* Fix to query return, functions, and tag declarator AST nodes correctly

+#### 2. Smoke test artifacts from the Cut Release PR
 
-2. Merge the PR
+The release builds can be find under the `artifact` zip, at the very bottom of the `ci` action page for each commit on this branch.
 
-3. Create a new release and tag pointing to the bump version commit using semantic versioning `v{x}.{y}.{z}`
+We don't have a strict process, but click around and check for anything obvious, posting results as comments in the Cut Release PR.
+
+The other `ci` output in Cut Release PRs is `updater-test`, because we don't have a way to test this fully automated, we have a semi-automated process. Download updater-test zip file, install the app, run it, expect an updater prompt to a dummy v0.99.99, install it and check that the app comes back at that version (on both macOS and Windows).
+
+#### 3. Merge the Cut Release PR
+
+This will kick the `create-release` action, that creates a _Draft_ release out of this Cut Release PR merge after less than a minute, with the new version as title and Cut Release PR as description.
+
+
+#### 4. Publish the release
+
+Head over to https://github.com/KittyCAD/modeling-app/releases, the draft release corresponding to the merged Cut Release PR should show up at the top as _Draft_. Click on it, verify the content, and hit _Publish_.
+
+#### 5. Profit
+
+A new Action kicks in at https://github.com/KittyCAD/modeling-app/actions, which can be found under `release` event filter.

 let myMathExpression = 3 + (1 * 2 / (3 - 7))
 ```
 
-Please if you find any issues using any of the above expressions or syntax
+## Tags
+
+Tags are used to give a name (tag) to a specific path.
+
+### Tag Declaration
+
+The syntax for declaring a tag is `$myTag` you would use it in the following
+way:
+
+```
+startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+```
+
+### Tag Identifier
+
+As per the example above you can use the tag identifier to get a reference to the 
+tagged object. The syntax for this is `myTag`.
+
+In the example above we use the tag identifier to get the angle of the segment
+`segAng(rectangleSegmentA001, %)`.
+
+
+### Tag Scope
+
+Tags are scoped globally if in the root context meaning in this example you can 
+use the tag `rectangleSegmentA001` in any function or expression in the file.
+
+However if the code was written like this:
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+rect([20, 0])
+``` 
+
+Those tags would only be available in the `rect` function and not globally.
+
+However you likely want to use those tags somewhere outside the `rect` function.
+
+Tags are accessible through the sketch group they are declared in.
+For example the following code works.
+
+```
+fn rect = (origin) => {
+  return startSketchOn('XZ')
+  |> startProfileAt(origin, %)
+  |> angledLine([0, 191.26], %, $rectangleSegmentA001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %) - 90,
+       196.99
+     ], %, $rectangleSegmentB001)
+  |> angledLine([
+       segAng(rectangleSegmentA001, %),
+       -segLen(rectangleSegmentA001, %)
+     ], %, $rectangleSegmentC001)
+  |> lineTo([profileStartX(%), profileStartY(%)], %)
+  |> close(%)
+}
+
+rect([0, 0])
+const myRect = rect([20, 0])
+
+myRect 
+  |> extrude(10, %)
+  |> fillet({radius: 0.5, tags: [myRect.tags.rectangleSegmentA001]}, %)
+```
+
+See how we use the tag `rectangleSegmentA001` in the `fillet` function outside
+the `rect` function. This is because the `rect` function is returning the
+sketch group that contains the tags.
+
