      Howdy :) Hmm...Yeah, I think somebody else found this too...yep, found
      this in my bugs list:

      * Matthew Ford: Support nested anon templates or return better error.

      Sorry about that...no conceptual reason, just a very bad scanner (which
      I do by hand since the delimiters are unrestricted). Actually, it
      might be in the stringtemplate action lexer itself not the thing that
      chunk up the template.

      Sure, send in a patch if you want :) Matthew will thank you too...

      Thanks for your interest...
