I don't know if there's much that can be done about this, but thought I'd mention it anyway.
Suppose you're trying to make a parameterised type, like type Elem[T any] blah... ex: https://go.dev/play/p/1tS1SCxTFP- but you forget the "any", and just write type Elem[T] blah... ex: https://go.dev/play/p/uig7iXsgZeU The error message, and the automatic reformatting you get, is a bit confusing: type Elem [T]blah... undeclared name T for array length I guess this is a fundamental ambiguity in the language. However, if an array length expression comes directly after a type name, *and* the array length itself consists of a single undeclared name, I wonder if the error message could give more of a hint? undeclared name T for array length, or missing constraint for type parameter (e.g. "T any") When there are multiple type parameters, it's fine: https://go.dev/play/p/_gmrdPzoWCD -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
