| Why do you expect $_ to contain anything in particular at this point?
| You've not assigned anything to it in this sub. $_ is a completely

| The arguments to a sub appear in @_.
Aaaarg! Thanks! In fact much of my learning Perl comes from reading
Automake, and scan_autoconf_config_files was precisely using $_ as if
it were the argument. So I really believed $_ was $_[0]. As
explained by Derek it worked precisely because
scan_autoconf_config_files was called with $_ as argument...
Thanks a lot for the clarification. I think I'll buy some Perl book :)
