Just to make sure I understand.  You're using FindTypes in a DeclContext using max_matches == 1.  But FindTypes will recurse in the DeclContext, so depending on the actual search implementation, you could have a situation like:

```
class A {
  class B {
       class C {
       };
   };
  class C {
  };
};

```

where if we do depth first we could start recursing down B, find A::B::C which is a match, note max_matches == 1 and return.  So this is really just FindFirstNestedType, I don't think you can make any claim about directness given how this is implemented.

I still think the idea of allowing a type search to be limited to a given type context is useful.  We usually do "FindWhatever" returning a list, and "FindFirstWhatever" returning some not described algorithm's chosen "first" match.  It's a little odd to add the "First" w/o the list version, however.
