I don't regard this as a low level versus VHLL issue - I regard it as a
matter of operators with side effects being too error prone.  Adding such
operators to Python has been discussed (it'd almost certainly be easy to
add), and rejected.

BTW, array operations optimize to the same thing as pointer arithmetic in
most C compilers, but the latter tends to be less clear.
