I think conditional expressions add to the orthogonality. You have
expressions and statements in Python, but statements can be conditional
and expressions cannot. This is unorthogonal. Algol 68 was orthogonal in
this respect, what you could do in statements was the same as what you
could do in expressions (there being no difference).
