Hi everybody,

I wonder about the performance of using a named reference compared of using
an additional argument of a predicate.  And how about a non-logical
variable?  Are they much slower?

Another question I ponder upon:

Do the constraint packages of ECLiPSe, e.g., ic use informed backtracking
techniques as backjumping and backmarking?  I guess not.

And it would be hard to implement them, wouldn't it?

Thanks, Uli
