Hi there! I worked on something similar a while ago: a compile-to-Go superset that adds some generic functions/methods. You may have come across it:
https://github.com/lukechampine/plyMy perspective was that when I find myself wishing for generics in Go, what I really want is not full-blown generic types and functions, but rather a few helper functions like map/filter/reduce, or converting a map to a slice, etc.
Having "true" generics is undoubtedly useful when you really need them, but the Go ecosystem has shown that they aren't strictly required in order to write large, maintainable programs. And you pay for them in the form of misuse. In that sense, I view generics much the same as operator overloading.
Anyway, I ran into some tricky edge cases when working on Ply and I'm curious how you address them. First, Go lets you define local types, i.e. with a function scope instead of top-level scope. You can't define methods on these, nor can you reference them in top-level functions. How does Fo handle the case where I want to call a generic function/method on a locally-scoped type?
The second issue I ran into was imports. I didn't devote a ton of time to this, but it seemed like it could be tricky to properly fetch both Go and Ply packages and pre-compile the Ply packages to Go. How does Fo handle this?
