Also a foul-smelling leech-infested swamp for those language designers and compiler writers who followed his example. (Come to think of it, plagiarizing a bad idea is probably the worse evil.)
There is absolutely nothing wrong with using = for assignment. The
problem in C was allowing an assignment within a conditional
expression. Now *that* was a bonehead idea! (Hingsight is 20/20, of
course.) Python does not allow that, so there is no problem. Nor do
most other languages allow it.
