MMD and redefinition

In Perl5, if I do:

 sub foo {return 1}
 sub foo {return 2}
 print foo();

I get a redefinition error, and a '2' on STDOUT. Can I assume this will
be the same in Perl6? i.e. can I write a test for pugs to check this?

Moreover:

 sub foo(Num $a) {return 1}
 sub foo(Str $a) {return 2}
 print foo(1),foo('a');

should have the same effect? Printing 2 twice? I don't expect MMD on
non-multi subs.
