Yes, but it is not clear yet what macro closures are exactly (Probably
it would make sense to inject the closed over declarations at the call
site, without adding them to the scope.)

It's not clear? We want to be able have a macro referring to utility
functions and these should be bind at the macro site and not call site.

Of course. What I mean by macro closure is the following:

Ast foo(){
     int x = 0;    // a 'closed over' variable
     return <[x]>; // escaping reference
}

macro counter(){ return $(foo())++; }

Actually

macro counter(){ return <[$(foo())++]>; }
