Who the heck is going to override arctangent? (No, don't tell me, I don't
want to know)
For stuff like this I don't see a point in having a vtable entry for the
transcendentals. atan is atan is atan. (Now, having said that, someone's
going to define it for matrices or something wacky like that) At absolute
worst I can see having a single vtable entry that gets passed in a
"transcendental function number" or have the vtable be double-level for
these, where there's just a "pointer to transcendental functions table"
entry in the main vtable, so everyone shares the same table unless they
want to get really extreme.
