That's right and `perl -d myscript` will run (via a bunch of evals and
other hairy stuff) irrespective of whether there are VMS DEBUG symbols
in your PERL.EXE. [.lib]perl5db.pl is a monument to obfuscated (and *quite*
useful) perl code.
If it does make for a speedup (you and Dan seem to be at odds over the matter)
then I'd say let's try to have CC/DEBUG builds turned off by default but
still requestable.
