This on its own is huge. Being able to point the ORM at the database
and have it auto-generate classes that'll give you accessors is really
a big timesaver.

DBIC covers some pretty complex SQL generation at this point. Sure, if
you're doing heavy OLAP/data mining work then you'll be hand-crafting
but for the majority (>99%?) of common use cases in development it'll
have you covered. Most ORMs have had decent prefetching for years so
that objection (lookups on related/joined/FK'ed) tables went away a
long time ago.

I'm working full time with Django and its modeling system and while
it's early days yet it does seem a much easier fit for me (I was in
the camp of "goddamit let me just use SQL already!" and had a slower
time adapting to the method calls & chained resultset notion. Also I
think Perl's syntax is a fail compared to python in this instance)
