If this is now switching to a discussion about a better alternative
for `dynamic-wind', these two names are certainly better in removing
the implementation aspect from the name. Maybe even some
(begin #:before (something)
code
#:after (something-else))
What I'd like to see in such a form is an optional way to forbid
re-entry, and a way to bind something in the pre code that can be used
in the body and in the post code. (But that implies a let-like form
rather than a begin-like one.)
