The spec is in the section "Class Properties", so in the strict sense, it would
not affect the semantics of struct tupleof property.

>From the view of implementation side, the inconsistency was introduced by
fixing issue 1418. By the fix class tupleof was changed not listing hidden
field but struct tupleof was not changed.

>From the user side, S.tupleof[$-1] is sometimes used to actually handle the
hidden context pointer.

Therefore, modifying tupleof behavior may affect not small code.
