[elephant-devel] Staus of the port of Ian's new functional toCL-SQL backend....

[Robert L. Read]

I have now committed an all-green solution for the CL-SQL backend to
elephant-unstable.

I don't know that it will help the Postmodern work much --- perhaps just
as a pointer for what needs to be done.

Nonetheless, it is ready for someone who wants to work on making
Postmodern work with elephant-unstable to review if they like.
