And I think that this attitude is key: any new language feature should
include some "good style" guidelines that, while not enforced by the
language, carry nearly the same weight. This is especially important when
the PEP needs to list, for clarity and completeness, what happens in
oddball use cases - a style section balances what's possible with what's

A lot of arguments against the PEP deal with odd abuses of the feature,
but IMO they overexaggerate the risks there. Most developers with even a
little discipline will avoid such uses, and if they don't care about good
style then they will write sloppy code despite what the language

If your company has a coding standard _and_ abuse becomes a problem, you
can add it to your coding standard (with emphasis on waiting for it to
really become a problem). At my current job we don't have a formal
standard at all, but every once in awhile we'll make style suggestions to
each other and it's the end of the issue. Not a big deal!
