What did you do?

enum Enum { a b }

fn test(x Enum) bool {
	return .a == x
}

dump(test(.a))

What did you expect to see?

What did you see instead?
Compile error

test.v:4:9: error: expected type is not an enum (`bool`)

      |            ~~

This would be tricky to implement, but it works in Swift (where the .a syntax was taken from), so it should be fixed.
