in thread Control Structure problem, mistake can't be found

Your comment seems funny to me (in a good way, really!) because I would normally code your example as 
my @lines = map { chomp; [split] } <SHEET>;

[download]
or, if I suspected that the "SHEET" could point to a very big file, 
my @lines;
chomp, push @lines, [split] for <SHEET>;

[download]
 both of which do need a _lot_ of perl knowledge to be read, aside from the CS knowledge you mentioned...
Update: obviously, blazar is right. and I should've written my examples as:
my @lines = map [split], <$sheet>;

[download]
and 
my @lines;
push @lines, [split] while <$sheet>;

[download]
because for was just wrong and because split already chomped the string...

    I personally believe that it wouldn't make a difference, unless you're already running Perl 6 since it has lazy evaluation by default; but in that case the syntax for the iterator would be completely different. Under Perl 5 you probably mean:

    my @lines;
chomp, push @lines, [split] while <$sheet>;

    (This reply is intended mostly for the benefit of the OP which is also the reason why I incidentally changed the filehandle to a lexical variable which is what one should use in most cases nowadays.)
