What are properties if not "getters" and "setters"? From the

Two methods named "num". No "get" or "set" in sight.

Sorry to bump, but it also isn't hard to use mixins to write 
more generic get/set.

import std.stdio : writeln;

struct Foo
{
        private int a;
        private int b;
        
        void set(string variable)(int x) @property
        {
                mixin(variable ~ " = x;");
        }
        
        int get(string variable)() @property
        {
                return mixin(variable);
        }
}

void main()
{
        Foo foo;
        foo.set!("a")(1);
        foo.set!("b")(2);
        writeln(foo.get!("a"));
        writeln(foo.get!("b"));
}

I suppose the errors will be more cryptic, since you don't check 
if the string referers to an existing member.

You provide only get/set that return by value. So you may need to 
generate getters/setters for const values, for ref values, for 
const ref values... And it would result in much more code for 
every object.
