Re: proposal: 404 method
András,
I think you have just discovered AUTOLOAD :-)
OTOH I don't know how the AUTOLOAD mechanism will work in Perl6 compared
to Perl5, or if it has been imlemented in Pugs (yet), but as far as I
remember, in Apocalypse 12 somewhere it says it will work the same(?) as
in Perl5, and what you have described works in Perl5 (if I understood
you correctly, which might not be the case).
