Yes. Perl will even warn you if the recursion stack gets too deep (I'm currently around 200,000 calls).

use strict; sub head_for_the_deep { my $depth = shift; print "Sinking to level $depth.\n"; head_for_the_deep($depth + 1); } head_for_the_deep(0);

Yes indeed you can.

It looks as if you're going to be doing a directory recursion, yes? You might want to check out this node, since its all about directory recursion and a tricky situation (which chromatic here above, shed some very good light on).
