in thread I usually debug via...

Generally a good approach, except that my programs are large and that could turn on hundreds of warnings. For me, I generally just need to turn on a few warnings at any given time and it's no big deal to hop around to those four or five that I've unmasked to comment them back up.

    My code is usually littered with stuff like print "Foo: ".Dumper(\$foo) if $debug>7;

    Often I write those in not knowing if I'll ever want that level of verbosity; usually I never have to crank $debug higher than 2 or 3. (1 just prints progress info usually, depending on what the app is; 2 gives more detail, and so on. 0 only prints actual errors, and undef suppresses non-fatal errors. Anything past 5 is dumping lots of big data structures.) Occasionally I do end up cranking it way up, though, and adding in extra print statements like the above, that I didn't originally anticipate needing.
