I have thought about this under a different angle, but with same conclusions, which can be formalized as: if you have a complex function , which can be represented as a composition of two or more functions, like: f(x,y,w,z) = a(x,y,w)*b(z) then its easy to see that if part of function f() input is not changing (x,y,w), then you don't have to re-evaluate the a() function to compute a final result of f(). Of course, this assuming that a() don't have any side effects. I think such kind of caching is more easily achievable in functional languages, than in smalltalk.
