Comment (by trironk3):

 I looked into handling the case of the given not having a ToString method
 or an operator<< method by just printing a pointer. Here's an example:

 struct blank { };
 int main()
   Log::Warn << "blank object: " << blank << std::endl;

 blank object: 0x7fff9fc551e0

 As it turns out, this can be easily implemented with Boost's
 has_left_shift method, but that was added in 1.48, and there are several
 files involved, so we can't simply yank some lines. If we ever start
 requiring a version of boost after 1.48, this would be a relatively
 trivial addition, but until then, I don't think it's worth anyone's time.
