in reply to big integers forcing me to be a C programmer: "range iterator outside integer range"

It's a silly point, but if the delta of your range is anything like a reasonable number, you can still use the iterator for; with a little ingenuity: 

my $x = Math::BigNum->new( 2 ) ** 1024;

for my $delta ( 1 .. 2 ) {
    print $x + $delta;
}

Whether that satisfies is a personal taste thing I think.
