Yep. There are some languages where this applies, because it’s a mathematical concept. The point is it’s the same ‘no value’ concept, which isn’t shared byimplemented the same way by all languages.
C is strongly typed, and uses pointers, so NULL sort of intrinsically has a value in C.
Same reason NULL != NULL. It makes sense if you understand how these values work.
That doesn’t smell right.
You can kinda think of it as null meaning undefined. In this case, “undefined does not equal undefined” seems easier for me to wrap my head around

ISNULL may be true, whilst NULL != NULL. NULL is not a value.
Ah, my brain was in C mode, where NULL is functionally 0. This is about the concept, which doesn’t apply equally to all languages.
