in reply to Deep recursion problem

DB:: is AFAIK the namespace of the debugger, so only the debugger will use that variable. If you want to recurse deeply, then just use "no warnings 'recursion';", as you already found out. Such a warning would have no value to you when you want to do arbitrarily deep recursion anyway.

And if you really need a limit, count the recursion yourself with an additional parameter (clunky but effective):

sub size_of_an_array { my($i, @array) = @_; ... return(++$i, 1 + size_of_an_array(@array));
