OK, I read the papers by McCarthy and the evaluator.

Do you know lisp ? Do you even know how to fork off another thread if
that is your issue with the heading ? Also, style cannot be decoupled
from skill of language. Even if you learnt all the C, you could not
write a C++ style virtual class in it unless you had the skill. The
most you would be able to achieve would be methods with function
pointers.

But you have one set provided to you on silver plate to use. Must I
provide you with all of them before you will activate your neuron and
lift your finger to explain how setf is implemented ?
