I made the changes you suggested and re-ran it. The program just comes

No warnings? Hmmmm.... Are you sure your program actually ran the new
code? That should have generated at least one warning. Is there any
chance you've redirected or closed the STDERR filehandle? You can
always add a line like this during development, if you need to be sure
the new code is being reached and that warnings are showing up:
warn "Yes; execution does reach this point";
Your code, though, prompts a question on syntax. In 2 places you specify
an underscore without a '$' in front of it.
That's the special underscore filehandle that's used in stat() and
filetests. Briefly, it means "the same file as we just tested", but
without going back to the OS to ask again.
