Using rakudo master.

The code:

# foo.pm:
module foo;
multi sub bar($foo, Int $bar) is export {
        say "bar";
}

# test.pl:
use foo;

bar(5, "asd"); # wrong parameter order

# result:
get_attr_str() not implemented in class 'Sub'
  in main program body at line 7530

What's expected is definitely the message concerning the failed dispatch
of the multi sub, but it's getting lost somewhere.
