AZed has asked for the wisdom of the Perl Monks concerning the following question:

I'm looking for the equivalent of -Wunused in C — or at least a moderate subset. I'd like to get a warning if a my variable goes out of scope without being used. I dug through warnings, perllexwarn, and perldiag, but didn't see anything appropriate.

There's a warnings::unused module, but the bug log for it notes that it can segfault, which makes me less than enthusiastic about trying it out.

There's also a Perl::Critic rule, but while I might eventually go that route and integrate it into my test files, that's a lot of work for what I was hoping to be a quick check.

Is there a simple method?
