dynamic-wind

[shaff@sesame.stanford.edu (Mike Shaff)]

ciao,
	I am looking for a portable version of 'dynamic-wind' (as documented in
MIT C Scheme), I know that Christopher Haynes reported on an implementation in
a paper entitled 'Constraining Control,' but I have not been able to find the
publication, so I would like to try and find a machine readable version.

	As a side question are the issues that are preventing this from being
part of standard Scheme?

(peace chance)
