So I'm getting a fairly typical "Use of uninitialized value", with the -w switch. How can I get more details, such as "Use of uninitialized value $foo"? 
#!/usr/bin/perl -w
use strict;
use Carp;
my $foo;
my $fum="testing";
print "$fum $foo\n";

Sometimes it is not so obvious exactly what value is the problem...
