| I would thus like to propose the following formalisation of the | ExplicitForall extension: What you suggest would be fine with me. Presumably ExplicitForall would be implied by RankNTypes and the other extensions? There is a danger of having too *many* choices. (http://www.joelonsoftware.com/items/2006/11/21.html) In particular, you might consider making ScopedTypeVariables synonymous with ExplicitForAll. Once you have given up the keyword, it seems a shame not to allow lexically scoped type variables! On ExistentialQuantification, I personally think we should deprecate the entire construct, suggesting GADT-style syntax instead. If you can form a consensus, go for it. Simon
