Well, it's certainly not entirely about that.  But an API that's hard
to misuse and easy to use correctly is a great boon when trying to
build and maintain systems that must behave as intended.  And, as
Nick's observed, it's all too easy for something like `sub with ($) {
... }` to be accidentally misused in ways that aren't easy to detect
in either the caller or the callee.
