type alias declared in .wit file does not generate a named type

[deadprogram]

I added a type alias to one of my wit files like this:

    /// size is a 2-element integer vector.
    /// It represents a width and height.
    record size {
        x: s32,
        y: s32,
    }

    /// point is a 2-element integer vector.
    /// It represents a x and y coordinate.
    type point = size;

The generated code substituted Size everywhere that the wit file used point which was not incorrect as far as typing/compilation, but did not achieve my objective of code readability which is why I created the alias.

What I expected was some Go code like this:

type Point Size

wit-bindgen for Rust did add named alias to generated code:

      /// point is a 2-element integer vector.
      /// It represents a x and y coordinate.
      pub type Point = Size;

Likewise C

// point is a 2-element integer vector.
// It represents a x and y coordinate.
typedef wasm_cv_types_size_t wasm_cv_types_point_t;

Interesting!

The generator does support aliases, but that code path is disabled by default due to how it's used pervasively in the default worlds.

I hadn't seen same-package aliases used in this way before. Happy to take a look.
