Comment (by js):
Ok, I thought you meant another example, because the one you gave was
pretty obvious to me. The [] operator comes before the & operator
(operator precedence). There is no explicit [] operator, so it falls back
to the C behaviour, where [] is just *(pointer + offset). As it needs a
pointer, it uses the Type* operator(). Then it can evaluate
someInts[arrayIndex] and takes the pointer of that and cast it. It all
boils down to operator precedence. Would it be more obvious to you if the
code were "(size_t*)(&(someInts[arrayIndex]))"? Because that's basically
how the compiler treats it due to operator precedence.
