Yes, using an index and a second call to getOverloads works, 
"finally".
No need to remix. Thx. I hadn't understood what you meant on SO.

One last question: is it possible to nest the calls to functions 
that take this kind of parameters ?

mixin template Bug()
{
      void bug0(this T)(){}
      void bug1(this T)(){}
      void allbugs(this T)(){this.bug0(); this.bug1();}
}

I've tried different parameters and templates and it never works.
