Mainly because languages generally only define a single left and right

I've considered adding a separate sub-vtable for trig ops, hanging off a
pointer in the class' base vtable, so multiple classes can share a single
trig vtable. I don't expect it to be overridden enough to be worth adding
another 128 bytes (or more) to each vtable we use. Most of the trig
functions can be "return function(SELF->get_float)" or something like
that.
