Range::SetOps - Provides set operators geared to work on ranges.
use Range::SetOps; say 10 (elem) (1.5 .. 15.2);
The standard Set operators work on Ranges by first converting them to lists and then applying the set operations to these lists. But Ranges can also represent a Range of possible values for which this type of comparison does not work well. The Range::SetOps module aims to provide operators based on the Set operators but geared to work on Ranges without list conversion.
The following operators have been implemented for continous numerical ranges and also tested on string and date range. They also work on Sets of Ranges like those returned by the (|) or ∪ operators.
The following operators already work for continuous Ranges as expected.
The following Operations will return Sets comprising one or more Ranges. When the Ranges within the Set overlap they will be combined into one larger Range.
