[Haskell-cafe] ANNOUNCE: sai-shape-syb Generic mapping to homogeneous types (etc.)

[Andrew Seniuk]

This package provides some support for dealing with polytypic data. It lets
you escape from the generics world and work with a homogeneous rose tree,
which can sometimes be convenient.

I realise a more experienced programmer would probably do this differently,
but anyhow it was useful to me and I've uploaded it.

http://hackage.haskell.org/package/sai-shape-syb

There are some examples at

http://fremissant.net/shape-syb

In particular, it supports GHC staged traversals, so for those trying to
work with the GHC AST this might be a helpful tool for filtering,
debugging, and suchlike.

Kind Regards,
Andrew Seniuk
