>>after having been in a position to maintain some Perl code before.
Sigh... You "supported some code" and know how modern Perl looks like?! :-)
Could you carefully explain e.g. the problems with Moose and the latest [syntax] extensions you find on CPAN?
To start with.
Making wild claims like that without support makes you seem like a language war troll or a complete asshat. To be taken seriously, show that you know what you make such big claims about.
Edit: And since you have nothing to say about the subject matter -- what is it in the Python culture that brews such fanatic language war trolls? (I assume you're a Python guy?)
