Title: Generation of construction functions guaranteeing algebraic invariants
on concrete data types

Aim: Although concrete data types are very useful in defining complex data 
structures, they are not always sufficient to adequately specify the data 
structures required by some algorithms. Often, only a subset of the concrete 
data type is in fact used since some invariants between the components are 
mandatory to ensure the correctness of the program. Now, many invariants can 
be described by using some equational theory. For instance, a sorted list is a 
particular representative of the equivalence class of lists modulo 
commutativity. The usual way to solve this problem is to use abstract data 
types or, better, private data types if one does not want to lose the ability 
of doing pattern matching. We propose to study the automatic generation of 
certified construction functions guaranteeing algebraic invariants on concrete 
data types, and develop an extension of OCaml with relational data types, that 
is, data types with invariants described by user defined equations.
