I've been learning about data structures by reading
the Programming Perl book. Here is a code snippet:
while ($line = <>) {
($who, $rest) = split /:\s*/, $line, 2;
@fields = split ' ', $rest;
$HoA{$who} = [ @fields ];
}
The part that confuses me is:
($who, $rest) = split /:\s*/, $line, 2;
I understand that it takes the input and splits it
into two parts along the regular expression, but I
can't figure out what the 2 means.
