I like it, since it means that things like [n .. n + length m - 1] work as expected when m is []. Or say 'map (array!) [bsearch x .. bsearch y - 1]'. Tangent: Of course, I would prefer the range be half-open, which is a pretty consistent standard in the rest of the world. I've had a number of off by one errors from this, and from Array.bounds. I guess it's too late to fix those, though, even if there were agreement that they need to be fixed. This is similar to the way python considers that xs[4:2] is valid, and is []. Of course python uses half-open ranges so xs[4:4] is still []. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
