I talked to Tom Stachowiak, who couldn't spot anything wrong with the
code.  I believe this is a bug in std.bind (or maybe std.traits.)  Has
anyone else seen this?

With 2.047:
----
import std.bind;
import std.stdio;

void g (int a, int b)
{
   int c = a + b;
}

void main()
{
   auto g1 = bind(&g, _0, _0);
   writeln(typeid(typeof(g1)));
}
---

gives
