I think it would be important to also show how SRFI-39-style sharing is handled.
Since sharing is not part of the standard yet, I would like to defer implementation of this. If an implementor would like to take upon himself the pain of doing this, I would be glad to add a link to his implementation in
the document ;-)
It would also be nice if pairs output from the expander would be eq? with pairs in the input, when that is the case with existing implementations.
I'm pretty sure I understand neither the formulation of, nor the reason for, this desideratum... :-)
