In fact experimental trunk of bison development try to generate parser
written with C++. C++ is absolutely not a limit, because we've changed the
generation method. In the past bison wrote code C in a file, now all the
code C is in the skeleton, which contains muscle (like macros), and that
muscles are substitute by bison, with this method every body could write a
skeleton to generate parser with a particular language (or with better
error recovery, ...). With this method, every programming language could
not have its own bison parser, but this will open bison to more languages.
