But Perl doesn't have a 'file' as datatype. Perl has filehandles. Just like it has hashes. You can have multiple filehandles, and actions on them don't interfere. You can have multiple hashes, and actions on them don't interfere either.

And while it's true that you can open multiple handles to the same file, when was the last time you saw a program opening multiple handles on STDIN or on a socket, to name a few common streams programs read from?

    You missed the point. If you have two subs that open file handles on a the same file they don't need to worry about each other. If however you have two subs that 'open' an each on the same hash, you are in serious trouble. I couldn't realy quoute you numbers on the use of either, but filehandles are certainly very different than each.

      No, I'm not missing the point. Unlike you, I was talking about filehandles, not files. Sure, you can open more than one handle on a file, but filehandles are used for more than files. Sockets and STDIN for instance.

        Well, you are playing semantic games. If you mean streams or sockets then talk about streams or sockets.
