( #3333=superdoc: print w/replies, xml ) Need Help??

Note that this strikes me as a much better use of a filter. It's not trying to find substitutable bits inside the source, just generating code from comments (though even being certain about what is a comment or not is not nearly trivial). I'd be even more appreciative if its directive syntax didn't look like code, particularly if it was clearly restricted to things the module can parse with 100% certainty.

If I were to write such a module, I'd wrap the debug statements in POD, because while that is just as non-trivial as comments, pretty much all existing POD parsers misparse source in known, predictable ways.

I don't think the debugging scenario makes brittle approaches excusable; the potential for subtle breakage introduced by filters would be doubly maddening if I'm already looking into another problem. I want to steer particularly clear of Heisenbugs in instrumentation code.

Makeshifts last the longest.
