A single-integer range is represented as the integer. A multiple-integers range from A to B is represented as "A-B". Examples:

 1
 1-3
 1-3, 5-8
 -Inf-2, 5-8
 5-8, 10-Inf
 -Inf-+Inf

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
