Although PEP-342 says foo(yield 42) is legal, Lib/test/test_grammar.py says:
BTW, It seems that foo(yield 42) written in ECMAScript 6 is OK.

Most PEPs are historical documents once they are final, so I don't think there is actually anything to fix here. But I could be wrong.

David is correct, most PEPs are historical records of design decisions that cease to be updated once completed. The language reference is the normative guide for current behaviour.
The exception is "informational" and "process" PEPs, which cover things that are not covered in the language reference, as well the occasional Standards Track PEP which ends up not being incorporated into the language reference properly (for example, until the import section was added to the language reference in Python 3.3, PEP-302 was the best available reference documentation).
