function pointers. Take a look at GUI module implementation for an example (you pass pointers to functions to buttons on creation, so that buttons know what functions to call when pressed).

Out of curiosity, how would you create a function pointer?

Turing:

fcn foo(x : int) : int
result x + 1
end foo

var fooPtr : fcn f(n : int) : int

fooPtr := foo

put fooPtr(0)
