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.
