Java is statically typed and it is ugly as hell. It also breaks stuff between major versions.
Implying that a language is doomed to be ugly or hard to evolve because it doesn't use static types is not a logical conclusion.
Besides, Perl 6 is not Perl 5 continued, and never pretended to be. Perl 5 continues to evolve (e.g. Moose) and is not getting uglier. You could argue that it was already ugly when it was created, but it is not growing uglier.
