Pandas ENH: Changing the regex engine pandas internally uses from re to regex or something else.

Feature Type

• [x] Adding new functionality to pandas

• [X] Changing existing functionality in pandas

• [ ] Removing existing functionality in pandas

Problem Description

I wish I could change the regex engine that pandas internally uses (python's native re module) in string methods to an engine that other libraries have - For example, regex PyPI link. I want to switch to regex or other regex engine because re has some limitations. Refer this answer.

Feature Description

Currently, below is possible: df['col'].str.match(pattern, x) To use regex instead of re, I know that I can do something like below: df['col'].apply(lambda x: regex.match(pattern, x)) But I don't want to loose pandas' string methods because they are vectorized and that's what make them pretty fast.

Alternative Solutions

Not sure about any alternatives here.
