If you think the fact that

	lst.extend([33])

can also be expressed as

	lst += [33]

compares to the difference between Python and assembly language, then
either you don't like Python very much or you love assembly  :-)

Don't get me wrong -- I very much like the idea of augmented assignment.
I'm just taking issue with it's use in the "list1 += list2" context (and
the like), where it's neither assignment nor concatenation. Seems to me
like an improper action for +=, much like overloading + to mean
multiplication.
