So yeah this does not gel so well with Spirit, maybe if boost::variant was like OCaml's polymorphic variants it would be a more feasible. Still though
I'm unfamiliar with polymorphic variants. Could you please give a brief explanation or reference? Is it any way related to the topic discussed here: http://groups.google.com/group/comp.std.c++/msg/8a90765a6e61ce82
this could have it uses in other places where client wouldn't normally add new internal (nonterminal) nodes.
Maybe. I guess with a grammar, the user would know all the nonterminal nodes; hence, this would work, AFAICT. This might be a huge (where huge refers to number of nonterminals in grammar) variant. Maybe it could be calculated from the grammar? But then, since it's used in the grammar ..., maybe that's not possible.
