Question: Specialized value types

1

Looking at: https://github.com/WebAssembly/component-model/blob/main/design/mvp/Explainer.md?plain=1#L638-L653 it shows that a `string` should be despecialized to a `list`, but it is not implemented like that in definitions.py, is that a conflict?

Support inline packages

Split 'use' inside worlds into 'use import' and 'use export'

13

This PR proposes to change how `use` works inside WIT `world`s, based on some initial discussion in [wit-bindgen/#822](https://github.com/bytecodealliance/wit-bindgen/issues/822). Currently, `use` can be used with the same syntax in both `interface`s...

Consider adding support for identifier aliases

Over in #311, @oovm points out that the fact that components broadly include identifiers in their public interfaces means that it's hard to fix naming mistakes in stable APIs. I...
