    for p in [

Mixing a list of regexs with implicit string concat feels aggressively misleading to the reader. Python has an option to ignore whitespace in regexes, so if we want to split the regex over multiple lines we should use a single multi-line string. Also we should check if it is faster to use several separate regexes or a single combined regex. The latter is usually better, but that depends on the implementation strategy of the regex engine.

Consider removing the implicit string concatenation, and investigate if using separate regexes is faster.
