Teach erlang:is_builtin/3 that erlang:apply/3 is built-in
erlang:is_builtin(erlang, apply, 3) returns 'false'. That seems to be
an oversight in the implementation of erlang:is_builtin/3 rather than
a conscious design decision. Part of apply/3 is implemented in C (as a
special instruction), and part of it in Erlang (only used if apply/3
is used recursively). That makes apply/3 special compared to all other
BIFs.
From the viewpoint of the user, apply/3 is a built-in function,
since it cannot possibly be implemented in pure Erlang.
