Hi all K Has someone already noticed/reported that suspend doesn’t work with typealias?
Example:

typealias MyType = (Any) -> Any
fun testFunction(block: suspend MyType) {}
//                      ^^^^^^^
// Modifier 'suspend' is not applicable to 'non-functional type'

Did you try typealias MyType = suspend (Any) -> Any? I think it wouldn't make sense in the way you did it since suspend adds another parameter to the function when compiling, so it's another type altogether... but then maybe typealias might also be compile time, so it might be possible.... but a bit hacky?

This is so by design.

@elizarov You mean like he did it, but typealias MyType = suspend (Any) -> Any should work, no?

[elizarov]

Yes. suspend Alias should not, while suspend FunType should work
