Not absolutely sure it will fit your needs, but it will at least advertise a
nice tool... The "moca" preprocessor allows you to add properties to
constructors of a sum type (e. g. associativity, commutativity, etc.). Example
from the webpage (*): type t = private | Zero | One | Opp of t
| Add of t * t begin associative commutative
neutral (Zero) opposite (Opp) end ;; Regards, Xavier Clerc
