That prototype isn't doing you any good. Turning on warnings reveals:
main::do_tree() called too early to check prototype at mneme line 41.
main::do_tree() called too early to check prototype at mneme line 43.
main::do_tree() called too early to check prototype at mneme line 14.
For the recursive calls at lines 41 and 43 to apply the prototype,
you need a declaration: sub do_tree($); before the sub definition.
For the call at line 14, put either the declaration or the the
definition earlier.
