Thank you all for the reply.

I hate to write boilerplate code:

[...]

import std.stdio : writeln;

mixin template f(T, string name, T value = T.init)
{
    mixin("T _" ~ name ~ " = value;");
}

void main()
{
    mixin f!(int, "x", 3);
    _x.writeln; // prints 3
    mixin f!(float, "y", 1.23f);
    _y.writeln; // prints 1.23
    mixin f!(string, "z");
    _z.writeln; // prints an empty string (== string.init)
}
