Re: Bison and C++

[Richard Stallman]

    It is fact possible to have the top-node in C even though the rest is
    written in C++:

That feature is useful for people who want to write in C++, but we are
not going to do that in Bison.  GNU Project policy is that programs
should be written in C rather than C++ whenever possible.  Bison is
going to remain a C program, overall.

The only place in Bison in which it is ok to use C++ would be an
optional parser skeleton in C++, provided for the convenience of C++
users.
