Just wondering a couple of things about core -> core plugins.

Is the second use case mentioned by pumpkingod there (tracking which rewrite 
rules are firing and when) actually possible using a core -> core plugin?

(it would be great to have this information fed into some sort of emacs plugin 
where one could drill down on specific functions to see what is happening)

Also, is Hoopl expected to be used on core -> core plugins, and, if so, is the 
infrastructure in place for this?

Thanks!  -Tyson
