Bug description

Would be nice to have that directly in the API documentation. Rather than having to dig for http://caml.inria.fr/pub/docs/manual-ocaml/expr.html and compute the actual associativity according to the structure of the operator.

I have a potential implementation (with precedence level too) here: #1167

#1167 merged onto trunk, so marking this one as done... for octachron's closure figures, obviously ;o)
