You can use string mixins.

template GenGetterSetter(string Type, string Name)
{
    const char[] GenGetterSetter = "    private " ~ Type ~ " " ~ 
Name ~ "_;\n" ~
                                   "    this(" ~ Type ~ " x)\n" ~
                                   "    {\n" ~
                                   "        " ~ Name ~ "_ = x;\n" 
~
                                   "    }\n" ~
                                   "    @property " ~ Type ~ " " 
~ Name ~ "()\n" ~
                                   "    {\n" ~
                                   "        return " ~ Name ~ 
"_;\n" ~
                                   "    }";
}

class Foo
{
    mixin(GenGetterSetter!("string", "bar"));
}

void main()
{
    import std.stdio : writeln;
    Foo foo = new Foo("bar");
    writeln(foo.bar);
}
