Personally I'd rather directly use #join - it's short as well and much
clearer what is happening - especially if #register and #summaryse
calls are in separate locations.

Why would I want to do that? Wouldn't it be much shorter to just use

Hm...
Generally I would rather implement those directly. The reason is
simply that this will reduce component dependencies of my applications
by one. When weighting using an external component (e.g. a gem) vs.
doing it internally the benefit must be higher than the cost for me.
YMMV though.
