I'm not sure, are you suggesting the grammar/parser enforces it that way, or
that it should be in PEP-8?

(I still can't help but go 'yecchh' whenever I see the code. It looks like
Perl's 'expr if expr' form, but it behaves quite different. Right now,
removing if/else expressions still looks like the best solution, to me :->
But gauging reactions (my own and others) to the actual if-expr in use is
the main reason I added those couple of lines to the compiler package.)
