    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).

    Can you? Yes!
    Is it a good idea? No
    As far as possible - you should avoid making recursive calls to a subroutine.
