Notes
... That shouldn’t be surprising. What might be surprising is that every SML program can be compiled down to a pure lambda calculus program! (Though that’s not exactly what the compiler actually does—it wouldn’t be efficient.) That’s true for many other functional languages, too. Lambda calculus is the ...
