Hi all, Does the current version (or future versions) of hugs support explicit kind information? For example, when composing 'category transformers' (whatever the beasts are) I would like to use a (restricted) type synonym along the following lines:
type C t23 t12 c x y = t23 (t12 c) x y in ... here is what hugs infers :info C -- type constructor with kind (* -> * -> * -> *) -> (* -> *) -> * -> * -> * -> * type C a b c d e = <restricted> but: When I define 'C t23 t12' as a category transformer, I get kind errors. What I would like to do is explicitely annotate t23 and t12 to have kind (* -> * -> *) -> * -> * -> *). ps: I do know that ghc6.x supports explicit kind information, but, (afaik) ghc6.x does not support restricted type synonyms and extensible records. So, a more general question would be: Are there any Haskell implementations out there that support o explicit kind information o restricted type synonyms o extensible records Luc This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.
