Hello!

I'd like to wonder if there's a provision in Perl to give out warning messages about unused variables. C has this. Lint has this for C in more detail. But, it seems Perl doesn't. It could go a ways for helping clean up code. 

--- Sample Code Start ---
#!/usr/local/bin/perl -W
use strict;
my $var_a;
print("Hello, world\n");
--- Sample Code End ---

No warning messages are created for this, despite $var_a being unused and irrelevant.

If there is a provision in Perl to do this, please email me. I would be happy to write a module to do this, but I think it probably would be quite difficult and involve lots of Perl internals that probably would change with Perl 6 anyway. Damian & Larry, are you listening? (grin).

Thanks to anyone who responds here or has a hint... Cordially, Kevin
