i'm now trying to improve implementation of cursor in postmodern backend.
it would be nice to optimize it for usage patterns of map-index, but
map-index implementation frightens me: is there a reason for such
complexity?
for example, just to enumarate index with two values it does calls l

I used CLSQL recording in the past when I have been debugging. I think
that is the best way to do it; I wouldn't want to put such a think in
Elephant, since it would be very backend-specific.

actually it's quite strange situation that you have *many* employees with
same name but you want just one (random one). i cannot imagine why one needs
this in real world..
or you're saying that all have different names, but it still does consing?
We have recently discovered some performance (and possibly other) problems,
you
might even call them bugs, with both map-index and the current
implementation
of cursors in the postmodern backend. Alex Mizrahi will reimplement things
in a new way
with the eye for performance, this work will probably
