Bug description

The grammar for "mod-constraint" includes:

type [type-params]  typeconstr  type-equation

it should actually be:

type [type-params]  typeconstr  type-equation { type-constraint }

because constraints are allowed on with constraints (although they don't actually do anything since they must match the definition and are not required if the definition does have them).
