If Perl 5 can support Lingua::Romana::Perligata<http://www.csse.monash.edu.au/%7Edamian/papers/HTML/Perligata.html>and let you type "
benedictum factori sic mori cis classum. instead of bless sub{die}, $class; then Perl 6 should be able to do it even better. I think it would be implemented through a set of macros. Unfortunately at the moment, the Perl 6 implementation that is the most advanced at the moment, Rakudo, does not support macros. (I'm not sure about Sprixel, Mildew, etc). So while the language specification would make it possible to use a different natural language as a base, it can't be implemented by the most natural method.
