No. The best you can do is document how to define a new Proto algorithm
from an old one:
struct Old : proto::or_< ... > {};
struct New : proto::or_< my_stuff, Old > {};
Now everywhere in your library that you have the Old algorithm
hard-coded, you need to make it a template parameter so that your stuff
can be used with an extended algorithm.
