I've added otherFunc(MF) to Marc Schütz's program:

alias MF = void function(int i);

void otherFunc(MF func) {
     func(42);
}

void main() {
     import std.stdio;
     MF myFunc;
     // you can also use the full `function(int i) { ... }` in the next line
     myFunc = (i) { writeln("i = ", i); };
     myFunc(42);

     otherFunc((i) { writefln("otherFunc called me with %s", i); });
}
