successful, and that we could build upon this by adding the optimal
implementations for standard library components. I have been using this as
an extension mechanism privately in this manner for a while and it has
worked well for me. I wanted to get other peoples views on this solution
before making the extension mechanism more widely used and optimised by
default for the standard library containers.
