But the right side of my brain (see Peter Keller's discussion in the
recent "importance of syntax" thread) finds it quite easy to recognize
this as a ternary op:
foo = (I_need_to_do_something_really_complicated_here()
if cond else
baz)
The whitespace below "foo" provides a visual hint, which is confirmed by
the nearby appearance of "if" on the second line. De gustibus non est
disputandum! (or not)
Many thanks to all responders!
