NAME
Range::Iterator - Generate an iterator object for range
VERSION
This document describes version 0.002 of Range::Iterator (from Perl
distribution Range-Iterator), released on 2019-04-23.
SYNOPSIS
use Range::Iterator;
my $iter = Range::Iterator->new(1, 10);
while (defined(my $val = $iter->next)) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can add step:
my $iter = Range::Iterator->new(1, 10, 2); # 1, 3, 5, 7, 9
You can use alphanumeric strings too since "++" has some extra builtin
magic (see perlop):
$iter = Range::Iterator->new("zx", "aab"); # zx, zy, zz, aaa, aab
Infinite list:
$iter = Range::Iterator->new(1, Inf); # 1, 2, 3, ...

METHODS
new
