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).

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

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

fooPtr := foo

put fooPtr(0)
