I have been using the Perl command line with a -ne option for years, largely to process text files in ways that sed can't. Example:

Has anybody found a good solution for lazily-evaluated lists in Perl? I've tried a number of ways to turn something like
for my $item ( map { ... } @list ) { }

Use an iterator or consider using Tie::LazyList from CPAN excellent book Higher Order Perl can walk you through those techniques.
A tie is as close as you can get in Perl 5.

I am a perl newbie,
Can I simply use 64-bit arithmetic in Perl?
For example
$operand1 = 0x ; // 48 bit value $operand2 = 0x ; // 48 bit value $Result = $operand1 * $operand2;
I am basically looking for a replacement for the int64_t in perl. Is there any...
