I noticed you can define a type alias with default generics,  such as `typealias MyCoolMap = HashMap<String, Any>` in Kotlin but when using Kotlin Multiplatform you can't do an `expect/actual` using a similar approach. For example: `expect class MyCoolMap` and `actual typealias MyCoolMap = HashMap<String, Any>` would not compile. The other way (define generics that are not used in a platform) also don't work.

My use case is that I have a type that has generics in one platform but not in all platforms - in a few we could just fallback to `Any` but Kotlin does not allow us to typealises it. API compatibility is a deal breaker, so I can't wrap the type either.

I'm wondering if anyone knows why that is not allowed? Any technical limitations or is it just a design decision?
