Currently we have two classes that actually should be fused together: parser and glr_stack. Both carry part of the parsing: (i) parser contains `parse`, which is the top-level of the parsing process, it uses yygetToken, etc., and (ii) glr_stack takes care of all the details (dealing with the stack), and also calls yygetToken. However if we fuse them together, we would get a large parser class, in the header file. So it is probably better to split this large class using the pimpl idiom. But then it appears that glr_stack is very close from being the impl of parser. Let's improve this. For a start... * data/skeletons/glr2.cc (parser::parse): Move to... (glr_stack::parse): here. (parser::parse): Use it.
