Agreed. Mandatory parentheses purely for readability are ultimately
futile - I bet I can write unreadable code even if the parens were
required :-)))))))))))))))))))))))))

The parentheses around genexps were (AFAICT) different - without them,
the grammar was ambiguous, so some way of disambiguating was needed.

+0 for mentioning parens around conditional expressions in PEP 8. But
it's aready covered by the general "code should be readable" in my
view.
