|go ahead... be a heretic|
I fully agree with JavaFan about having to remember (and let's not forget, also having to install) various new policy modules - they don't seem to be worth the trouble for me.
A few minor nits:
IMHO 'nextgen' (and also 'Modern' in Modern::Perl) is a bad toplevel namespace; a Policy:: or policy:: namespace would fit better. Hubris is supposed to be a virtue for Perl programmers, but only while writing code, not while interacting with the rest of the world.
autodie (will be core in 5.12 anyway)
That sounds as if 5.12 were the future. It's not, it's been released almost half a year ago. That said, autodie was also included in 5.10.1
Another thing to mention is that loading utf8 does more harm than good, unless you also set up decoding and encoding IO layers for input and output.
