> It's one of the most primitive instructions, why shouldn't it be available when needed? I see what you're saying, though I don't find this a compelling argument.

Just because something is a primitive operation doesn't mean you want to include it, especially not if it's more difficult to enforce guarantees your language would like to make about valid programs.
