Re: selecting N random lines from a file in one pass

Off-topic, but I can't resist. Every time I see a C-style for loop in someone's Perl code, I die a little inside. How about this instead:

for my $i ( 0 .. $#sample ) {
    print "[$i] '$sample[$i]'\n";
}

Old habits... =) Anyone know if that's actually faster or slower in execution? What about memory consumption?	[reply]

Don't worry about it. If there are any differences, they are so small you would never see them outside of a crazy benchmark.	[reply]

Every time I see someone use `$#array` just to be able to use `foreach` to loop over the indices and avoid using a C-style loop, I die a little.	[reply] [d/l] [select]
