First, I wouldn't have expected scalar to take two arguments. True, modern perlfunc pages document this, but it's certainly unexpected to me. Second, I dislike modifying $_ in a map, because I believe a map to be applicative, not side-effect-ish. -- Randal L. Schwartz, Perl hacker Be sure to read my standard disclaimer if this is a reply.

I'm not sure how that works, but it seems like the map /(.*)/, <> is more perlish. Also, it's shorter. Harley J Pig	[reply]

Why not my @result = map scalar(chomp, $_), <$FH>? That use of scalar gives me the creeps! Isn't this equivalent and less obfuscated? `my @result = map {chomp; $_} <$FH>;` [download] Update: or for that matter whats wrong with `chomp(my @result = <$FH>);` -- Murray Barton Do not seek to follow in the footsteps of the wise.
