The question of typing is somewhat orthogonal to that of naming value
objects versus storage locations. There are strong stactic typed named
value languages like ML. They even require different operators for int
and float arithmetic, just like assembler.
Assemblers also type data versus address registers and may have signed
versus unsigned int operations. But most typing has to be done by the
programmer, just as C requires the programmer to do garbage collection.
