Works:
zoffix@VirtualBox:~$ perl6 -e 'class Foo { ... }; class Foo { }'

Redeclaration error:
zoffix@VirtualBox:~$ perl6 -e 'class Foo { … }; class Foo { }'                  
                                                                                
                                                                                
               
===SORRY!=== Error while compiling -e
Redeclaration of symbol 'Foo'

    expecting any of:
        generic role

Even though it can be used as a stub:
zoffix@VirtualBox:~$ perl6 -e '…'
