You do that by defining a resource that represents the group of things you
want to operate on.  It can be tricky sometimes, but it's doable.

BTW, lazr.restful is only REST-ish because it defines backdoor function calls.
I've been getting a lot of mileage out of the restish.io library (which
conversely, allows for pure REST implementations) and JSON representation.  It
lacks some of the nice collections support in lazr.restful, but it's also
*much* more lightweight, integrates well with WSGI, and it's not hard to add
support for collections.  I don't much care about WADL though, so I'm ignoring
that whole thing.  Also, it does help to have PATCH support, which takes a
small bit of hacking, but it's worth it.
