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

+After it runs you should just need the push the branch and open a PR.
 
-The PR may serve as a place to discuss the human-readable changelog and extra QA. 
+**Important:** It needs to be prefixed with `Cut release v` to build in release mode and a few other things to test in the best context possible, the intent would be for instance to have `Cut release v1.2.3` for the `v1.2.3` release candidate.
 
-2. Merge the PR
+The PR may then serve as a place to discuss the human-readable changelog and extra QA. The `make-release.sh` tool suggests a changelog for you too to be used as PR description, just make sure to delete lines that are not user facing.
+
+#### 2. Smoke test artifacts from the Cut Release 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.
+
+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_.
