hi,
first here is why i think n+k patterns are problematic;
1) they lead to some parsing awkwardness (e.g. when n+k pattern bindings
are involved, but those don'treally make much sense anyways)
2) in haskell as it is, patterns are associated with algebraic
datatypes, and n+k patterns may

The n+k pattern issue inspired endless debates on the Haskell
committee and this feature was considered for removal in nearly every
iteration of the Haskell report. We all agreed that n+k is extremely ad-hoc but
that certain programs can be expressed slightly more elegantly using
