Toot

I wish this (strange) code would show a diagnostic like “Did you mean to pre-declare ‘B’?” rather than “Redeclaration of symbol ‘B’.”

class B {}

class A {

has B $.b;

}

class B {

has Mu $.something; # doesn't matter; i just want to put something here for this example

}

The fix is to create a stub class (class B {…}), but this is not obvious at first glance. (In this case, we could also fix it by merging the two definitions of B and moving B to appear before A, but I can’t do that in my actual code.)

@julia

Good point. If the class being re-declared is empty, the error message should suggest stubbing the class.

Could you make an issue for that?
