readValidInt() is a function template that takes two
information:
1) The validator as its alia

There is the relatively newer alias syntax which is more
intuitive:
alias Validator = bool function(int n);
Great. This is easily re

Now its clearer to me. You want delegates

I dont know much about functional programming, but what stops you

I'm just learning D, so please bear with me if I'm asking

Consider the following code skeleton:
// in part A of the application...
//
-
alias bool function(int n) validator_t;
bool isEven(int n) { ...
