TCO = Tail-Call Optimization, so you can use recursion without
blowing up the stack ...
But recursion isn't confusing, it makes for elegant/textbook
programs, it's not really a layer of indirection, is it?
Nested macros tho are like the definition of that (extra
layer/indirection) since instead of
you program -> a program -> that does stuff
it is
you program -> a program -> that expands into a program ->
that does stuff
It makes the programming language programmable ...
