RESTful dispatch question

I've been looking at RESTful dispatch tools for use with CP
and I'm not seeing 
any that will dispatch where you have multiple parameters in
the URL, like 
/Y/M/D in the following (consider that /M/D are optional as
well!):

/posts/Y/M/D/user/ID

Everything I'm seeing expects there to be only one
parameter.  This would work 
for most of the cases but there will be exceptions.

There's a Selector module that works with WSGI applications
that will handle 
this just great but using it inside CP looks like you'd have
to write a 
straight WSGI application and lose functionality provided by
CP as a result 
(i.e. logging, etc.)

It appears from my limited look so far at WSGI that you have
to get modules to 
do everything (i.e. paste.translogger for logging) and you
end up gluing a 
bunch of stuff together that CP already supplies.

How do you deal with this situation?

Well, you can handle those URLs directly with CP using the
default method:

rial#Partialmatchesandthedefaultmethod

If that isn't enough, you can used the provided Routes
dispatcher or
the HTTP MethodDispatcher.

If you would like to use Selector, perhaps it could be
hooked up to
CherryPy as a custom dispatcher, like the one for Routes. 
That would
be a welcome contribution to the collection of code at
tools.cherrypy.org.

Yes, WSGI itself is really something that the application
developer
shouldn't have to deal with on a high level.  It is useful
for
framework/tool authors though.
