** New features
*** Returning the error token
When the scanner returns an invalid token or the undefined token
(YYUNDEF), the parser generates an error message and enters error
recovery. Because of that error message, most scanners that find lexical
errors generate an error message, and then ignore the invalid input
without entering the error-recovery.
The scanners may now return YYerror, the error token, to enter the
error-recovery mode without triggering an additional error message. See
the bistromathic for an example.
*** The bistromathic features internationalization
Its way to build the error message is more general and is easy to use in
other projects.

** Backward incompatible changes
TL;DR: replace "#define YYERROR_VERBOSE 1" by "%define parse.error verbose".

It makes little sense to use this feature without enabling LAC (lookahead
correction).

*** Deep overhaul of the symbol and token kinds
To avoid the confusion with types in programming languages, we now refer
