Performance improvements are nice, but I imagine there are more
important things to add to CLSQL (prepared statements, improved
support for non-ASCII charactersets)  I had the time.

I'd say the first step would be to add basic support for cursors in
CLSQL. Then, the syntax for the loop macros could be extended to
support them. You're right. There is no documentation on loop
macros. The support in CLSQL came as a result of many hours of
exploring undocumented symbols and functions in the various supported
Lisp implementations.
