Out of curiosity, do you plan on somehow dynamically building new
actions to associate with new productions? This is something I can't
imagine being easy in any non-functional programming language. And
without this ability, I have a hard time imagining how dynamically
modifying a grammar would be useful. Changing whether or not something
is considered a keyword by the lexer at runtime doesn't require
modifying the grammar itself, does it?
Also, what do you want to happen if a new production introduces an
ambiguity into your grammar?
