PEP 0008: What does the BDFL mean by 'in true XP style'?

Question

I was reading PEP 0008 (the python style guide), and came across the following reason to not follow any rule in the style guide.

It says that it's ok to break a rule to

be consistent with surrounding code that also breaks it (maybe for historic reasons) -- although this is also an opportunity to clean up someone else's mess (in true XP style).

What does 'in true XP style' mean?

Answer 1

As mentioned in the comments, XP here refers to Extreme Programming. I think the comment "an opportunity to clean up someone else's mess (in true XP style)" may be half tongue-in-cheek. While refactoring and design improvement are core practices in XP, many critics argue that it often leads to the same code needing to be rewritten several times.
