my.regex.meta: Internal Regex Metatypes

This subpackage contains a variety of classes (and a few constants!) for representing, analyzing, and modifying regular expressions in a structured manner. As opposed to the internal types within Python’s standard re library, these types are not built to support regex evaluation; instead, they provide a more modern, ergonomic way to work with regular expressions before they’re evaluated.

These modules are described as “internal” because they were clearly designed with the specific needs of RegexStore in mind–namely, optimizing branching expressions (e.g. a|b) and debugging complex expressions of any kind–but they are made available in the public API nonetheless. If you extend them, please consider submitting a PR so that others can benefit from your work!
