Below works
-----------

import std.stdio;

int calculate(string T)(int a, int b) if(T == "add")
{
    return a + b;
}

int calculate(string T)(int a, int b) if(T == "subtract")
{
    return a - b;
}

void main() {

    int a = 10;
    int b = 20;
    std.stdio.writeln(calculate!("add")(a, b));
    std.stdio.writeln(calculate!("subtract")(a, b));
}


Output
------
30
-10
