NAME
Range::HashIter - Generate a tied-hash iterator for range
VERSION
This document describes version 0.001 of Range::HashIter (from Perl
distribution Range-HashIter), released on 2019-05-12.
SYNOPSIS
use Range::HashIter qw(range_hashiter);
my $iter = range_hashiter(1, 10);
while (my ($key, undef) = each %$iter) { ... } # 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
You can add step:
my $iter = range_hashiter(1, 10, 2); # 1, 3, 5, 7, 9
You can use alphanumeric strings too since "++" has some extra builtin
magic (see perlop):
$iter = range_hashiter("zx", "aab"); # zx, zy, zz, aaa, aab
Infinite list:
$iter = range_hashiter(1, Inf); # 1, 2, 3, ...
DESCRIPTION
PROOF OF CONCEPT.
This module offers a tied-hash-based iterator that you can use using
while() and each(). It's most probably useful as a proof of concept
only.
FUNCTIONS
