This is essential for Perl programming, along with perl -MO=Lint -c <file>. The downside is that it is slow and takes away the fast turnaround times you're used

  I've been using "perl -tTW" along with "use strict; use warnings; use sigtrap;" before I found out about Perl::Critic, which works nicely with flymake (http://www.gnu.org/software/emacs/manual/html_node/emacs/Flymake.html http://www.gnu.org/software/emacs/manual/html_node/emacs/Fly...). None of it has seemed to slow me down too much. The thing about these tools (along with other checkers, warnings, errors, etc), for me at least, is they tend to be corrective. I learn not to keep making the same mistakes, if for no other reason that to avoid the "pain". This is just icing on top of the fact that these tools can be automated, especially to prevent code from being checked in or merged when it violates these checking systems.
