The code should be rejected. It's a compiler bug.
But, you can do what you want as follows.

import std.stdio, std.typetuple;

struct A {
     @("1") int a;
     @("2") int b;
     @("3") int c;
}

auto bar(alias expr)() @property {
     writeln(expr);
}

void main() {
     A a;

     foreach(it; __traits(allMembers, A))
     {
         enum tp = [__traits(getAttributes, mixin(`a.` ~ it))];
         // or
         alias tp = TypeTuple!(__traits(getAttributes, mixin(`a.` 
~ it)));

         writeln(`passing: `, tp[0]);
         bar!(tp[0])();
     }
}
