I'd have thought only Forth programmers would be prone to that!
It would surprise me greatly if it's really true that *most*
people would read it that way. Especially given that, in real
code, you're not going to be looking at abstract names like
exp1, exp2, exp3, but (hopefully) something a lot more
meaningful.
Can you honestly say that you would read
return red_value if color == 'red' else blue_value
as
if red_value:
return color == 'red'
else:
return blue_value
?
