Hi John. Are you sure of that? I've just answered a private question about use of $_ from a guy who was insecure about its use. I said that the only places it was /altered/ was in 'foreach', 'while (<*>)', and (kinda) in 'map' and 'grep'. That's all I could think of. I agree with your list above, but would add the obvious qr//. A definitive list of this sort of thing would be useful, if only for evangelising Perl. To summarise: Where else does Perl implicitly modify or use $_? Where else does Perl implicitly use regular expressions? Any thoughts? Anybody?
