There seem to be other places where Python is beginning to require parens even though they aren't strictly necessary to resolve syntactic ambiguity. In the style guide only, I hope. The parens that are mandatory in a few places are necessary to resolve ambiguity.

Technically, I believe the first place where this did not apply was
list comprehensions, back in 2.2, since (for example) [x, y for y, x
in whatever] could have been syntactically disambiguated but (quite
reasonably, IMHO) [(x,y) for y,x in whatever] was mandated instead.
