A module calculus enjoying the subject-reduction property. (Preliminary Version)

Abstract : The module system of SML is a small typed language of its own. As is, one would expect a proof of its soundness following from a proof of subject reduction, but none exists. As a consequence the theoretical study of reductions is difficult, and for instance, the question of normalization of the module calculus can not even be asked. In this paper, we build a variant of the SML module system --- inspired from recent works --- which enjoys the subject reduction property. This was the initial motivation. Besides our system enjoys other type-theoretic properties: the obtained calculus is strongly normalizing, there are no syntactic restrictions on module paths, it enjoys a purely applicative semantic, every module has a principal type, and type inference is decidable. Moreover we conjecture that type abstraction --- achieved through an explicit declaration of the signature of a module at its definition --- is preserved.
