Given these two classes:
class Test1 {
    class A {}
}

class Test2 {
    class A {}
}

Rakudo fails with the error ``Re-declaration of type A at line 7, near
"}\n"''. I think this is related a problem in the interactive
interpreter. If you declare a class in a line, and then definen a
class with the same name in a subsequent line, you will get a type
redefinition error like the script above:
$ ./perl6
> class A {}
> class A {}
Re-declaration of type A at line 2, near ""

I'm not familiar with Rakudo's guts, but to me it looks like class
information is stored in a more global scope than lexical scope, and
apparently without the full path to the type, only the local name.
