Comment (by jdemeyer):
I'm not happy with the change of `_eval_` to `__call__`. You cannot expect
every function which wants an `algorithm` argument to override `__call__`.
Especially now that more and more non-trivial logic is going into the
`__call__` method of `BuiltinFunction`.
I might make a lot more sense to move all this `algorithm` stuff to a
custom `_evalf_` function, which ''does'' support an `algorithm` argument.
In order words: I think the general question of how to handle `algorithm`
arguments in symbolic calls should be answered first.
