Template bind
Allows you to bind arguments to a function at different positions
template bind(alias pred, BoundArgs...)
;
E.g. bind arguments to the 1st and 3rd parameter and call:
void f(int a, int b, int c) {}
alias a = bind!(f, 1, void, 3);
alias b = (int second) => f(1, second, 3);
a(2); // calls f(1, 2, 3);
b(2); // calls f(1, 2, 3);Contained Functions
