internal: KCL modules, part 1 (#4149) Addresses #4080. (Not ready to close it yet.) # Important Requires a fix for #4147 before it can work in ZMA. # Overview ```kcl // numbers.kcl export fn inc = (x) => { return x + 1 } ``` ```kcl import inc from "numbers.kcl" answer = inc(41) ``` This also implements multiple imports with optional renaming. ```kcl import inc, dec from "numbers.kcl" import identity as id, length as len from "utils.kcl" ``` Note: Imported files _must_ be in the same directory. Things for a follow-up PR: - #4147. Currently, we cannot read files in WebAssembly, i.e. ZMA. - Docs - Should be an error to `import` anywhere besides the top level. Needs parser restructuring to track the context of a "function body". - Should be an error to have `export` anywhere besides the top level. It has no effect, but we should tell people it's not valid instead of silently ignoring it. - Error message for cycle detection is funky because the Rust side doesn't actually know the name of the first file. Message will say "b -> a -> b" instead of "a -> b -> a" when "a" is the top-level file. - Cache imported files so that they don't need to be re-parsed and re-executed. 2024-10-17 00:48:33 -04:00			`export fn increment = (x) => {`
