Hmmm.  I guess that we're both right, just answering different

I was curious about what the overhead of using Moose would be,
compared to basic Perl.  How many additional distributions would I
need to install.

I started with my perlbrew'ed perl 5.14.2, then used cpanm's
local-lib-contained functionality to install everything that wasn't
part of the core (making sure I wasn't cheating by having already
installed random bits and pieces).

The result was 22 add'l distro's.  It wouldn't surprise me if other
perl's would pull in a few more/less distro's, depending what's in
their core.

Moose *is* a bit of a gateway drug, however.  There's a *big* step in
my mind between using Moose and a tasteful set of MooseX to{ol,y}s
versus getting involved with heavier things like MooseX::Declare and
it's Devel::Declare underpinnings.  Developing taste is a journey.

The cpan testers link counts "Modules".  That's probably going to
cause some difference too.
