is there a general solution to pass multiple arguments to a function via a mixin?

see below for a partial solution using Alias, which fails for the last case below:

void main(){

  import std.stdio;

  string a="A";

  string b="B";

  writeln(a,b);// OK (prints "AB")

  writeln(&a,&b);//OK (prints both addresses)

  writeln(mixin(`a,b`));//prints "B"

  import std.typetuple;

  writeln(mixin(`Alias!(a,b)`));//OK:prints "AB"

  //writeln(mixin(`Alias!(&a,&b)`));//CT Error: expression & a is not a valid template value argument

}
