Are you sure we shouldn't wait until we use Wasm GC?

By "first class function", do you mean closures? Those might be easier to implement in Wasm GC, since the heap doesn't have to be dealt with manually, and closure objects...

Also, the current test should already work: see [here](https://www.assemblyscript.org/editor#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).

I don't quite understand what you mean.

Oh, do you mean creating a new `Function` object for each returned inner function, instead of a single object?

Number one seems more plausible, since a cast would fix it.

Good point, although I thought that would be a niche case in comparison to the RT growing memory. Do you think a handler can/should be integrated with ESM/raw bindings to...
