Let the callee be configurable instead of depending on `arguments.callee`.

Question

Let the callee be configurable instead of depending on `arguments.callee`.

First, it's deprecated and considered legacy. Second, not all callers may necessarily call it at the top level, so you can end the stack traces at the API boundary.

arguments.callee references the currently executing function. I'm not sure why it was arguments.callee instead of AssertionError in the first place; that line is from 2013, well before my time here.

Anyway, the AssertionError function is merely the default starting point to remove frames from the stack trace. It can already be overridden by passing a function as the ssf parameter.

Okay. Thanks! (I crossed up arguments.caller with arguments.callee. Haven't dealt with those in a while.)
