DESCRIPTION

This module provides a function that can optimize a list of values into range objects.

FUNCTIONS

rangify

Takes a list of values and makes them into ranges.

For example:

    rangify(1, 2, 3, 5, 7, 9, 10, 11, 15);

returns the following ranges:

    1-3
    5-5
    7-7
    9-11
    15-15

It returns a list (in list context) or an array reference (in scalar context) of Set::IntRange objects.

Duplicate values in the input list are ignored.
