Warnings

breaking The regex module is incompatible with PyPy due to differing string storage methods.
Fix: Use CPython for compatibility.
gotcha The regex module releases the GIL during matching, which can lead to concurrency issues if the string is modified during matching.
Fix: Ensure the string remains unchanged during matching when using concurrent=True.
