Thanks for the patch that you proposed in
I don't use C++, so you'll have to bear with me on some dumb
questions.  Perhaps some other contributor who knows C++ well can also
chime in.

* How much is this patch tied to Boost?  Can it be used easily with other
  C++ libraries?

* What sort of documentation should appear in the Bison manual?

* Why is there a limitation on what types can appear?  (They can't
  have angle brackets, apparently.)  Can this limitation be removed?
