How useful is dynamic-wind in real world programming?

Question

I have read a bit and tried to understand dynamic-wind but am not quite sure how it can be employed in a real world application.

Any insight on the subject will be very helpful.

Answer 1

The first thing that comes to mind is Olegs argument against call/cc which also mentions Dynamic wind "pros" and cons. It's mostly negative so it will be interesting to see if anyone else answers with other material.
