[jhc] Multi parameter type classes

Is there also anonymous access to the JHC bug+feature-tracker? I like to add a request for multi-type parameter classes. These are necessary to compile NumericPrelude, what most of my signal processing code is based on. I need them for instance for vector spaces in order to write frequency filters and interpolations that work on both mono and stereo signals. I do not need functional dependencies. numericprelude$ grep -rh LANGUAGE src | sort --unique {-# LANGUAGE FlexibleInstances #-} {-# LANGUAGE MultiParamTypeClasses #-} {-# LANGUAGE NoImplicitPrelude #-}
