May not be intentional, but erlang:apply/3 is a strange
creature which is not implemented in the same way
as all other BIFs. Part of apply/3 is in implemented
in erlang.erl:

apply(Mod, Name, Args) ->
    erlang:apply(Mod, Name, Args).

(This Erlang code will be called if you apply apply/3.)

What do you think? Should erlang:is_builtin(erlang, apply, 3)
return true? If so, why?
