NAME
Range::ScalarIter - Generate a tied-scalar iterator for range
VERSION
This document describes version 0.001 of Range::ScalarIter (from Perl
distribution Range-ScalarIter), released on 2019-05-12.
SYNOPSIS
use Range::ScalarIter qw(range_scalariter);
my $iter = range_scalariter(1, 10);
while (defined(my $i = $$iter>)) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can add step:
my $iter = range_scalariter(1, 10, 2); # 1, 3, 5, 7, 9
You can use alphanumeric strings too since "++" has some extra builtin
magic (see perlop):
$iter = range_scalariter("zx", "aab"); # zx, zy, zz, aaa, aab
Infinite list:
$iter = range_scalariter(1, Inf); # 1, 2, 3, ...
DESCRIPTION
