Previously in a member expression like `foo.x` or `foo[3]`, `foo` had to be an identifier. You could not do something like `f().x` (and if you tried, you got a cryptic error). Rather than make the error better, we should just accept any expression to be the LHS of a member expression (aka its 'object').
This does knock our "parse lots of function calls" from 58 to 55 calls before it stack overflows. But I think it's fine, we'll address this in https://github.com/KittyCAD/modeling-app/pull/6226 when I get back to it.
Closes https://github.com/KittyCAD/modeling-app/issues/7273
Preparing for the removal of positional functions from the language. The first big step is to change all our KCL code examples, test code, public samples etc to all use keyword functions.
Apologies for how large this PR is. Most of it is:
- Changing example KCL that defined its own functions, so the functions now use keyword arguments rather than positional arguments. E.g. change `cube([20, 20])` to be `cube(center = [20, 20])`.
- Some parts of the code assumed positional code and didn't handle keyword calls, e.g. the linter would only check for positional calls to startSketchOn. Now they should work with either positional or keyword.
- Update all the artifacts
This does _not_ remove support for positional calls. That will be in a follow-up PR.
