because your point is moot with the much better solution. the OP is
wandering around the woods with IO::File and handles and he doesn't even
need them. also i didn't even mention that if you do use handles, you
can do direct method calls which are even better than indirect with
{}. indirect method calls are just fugly in perl and can cause problems
in some cases (not with print but with regular classes/methods. so it is
BEST to never even use them if you can help it. $fh->print works as long
as the handle is opened normally and you load the IO::Handle module (or
something similar). hell, i rarely use anything but write_file these
days so don't have to worry about it.
