Re: [lisp] I-D Action: draft-saucez-lisp-itr-graceful-01.txt

Tis is an interesting piece of work.
Once we clear the current blocking documents, I look forward to 
discussion on the list of the pros and cons of the ideas presented herein.

Yours,
Joel

PS: As a minor item, when you respin this document, please shorten the 
abstract.  A lot.
