And why not "as", i.e. "t as x", as I explained once in a previous post. I never did get an explanation as to why this wasn't an better solution. It reuses a rarely-used keyword in a perfectly backward-compatible way. I think it's simply a typical case of a new (and not necessarily terribly crucial) language feature muscling in on the limited "ultra-convenient" concrete syntax that's available!

But why did you use the same character ":" for types and labels ! whit not (for instance) x:t to say that x as type t and l#x to say that x as label l the syntax l#x:t is much better than l:x : t !! I know that # is allready used for methods ... but some characters are still usable: ~ £ it looks like the l of labels (but its ascii code is greater than 128, but is this really a problem ? probably ?) -- Christophe Raffalli Université de Savoie Batiment Le Chablais, bureau 21 73376 Le Bourget-du-Lac Cedex tél: (33) 4 79 75 81 03 fax: (33) 4 79 75 87 42 mail: Christophe.Raffalli@univ-savoie.fr www: http://www.lama.univ-savoie.fr/~RAFFALLI
