compose
A function that takes two functions and returns the composition of them. In mathematical notation (f o g) x = f(g(x))
Using /DeimosTemplateLibrary:
instance TFunctional(boolean, boolean, int) lambda;
boolean not(boolean b) { return !b;};
boolean negative(int n) { return n < 0;};
boolean() isNatural = lambda.compose(not, negative);
Obs.: This may work according to the kind of functions passed (e.g. closure or combinator) because of current implementation of /DynamicClosures.
