In this release, only the programming language is implemented, but I am interested to hear remarks from the members of this list to try to get the best possible initial design. More information, development plan, download and manual are available at http://www.lama.univ-savoie.fr/~raffalli/pml The main features of the language are: - great cartesian product unification (records, modules and objects are the same, arrays are missing and will not be unified) - polymorphic variant needing no type annotation (but it is a good idea to use some) - two kinds of inheritance: open inheritance and multiple (closed) inheritance (read the manual to know what this mean) both for records and pattern-matching which are dual in PML. - etc. -- 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
