Re: [eclipsefp-develop] GHC 7 support in Scion

[JP M. <jpm...@gm...>]

Yes, I had started looking at it and did the same thing as you (play
around with list-tries, ghc-syb-utils, etc). Have you notified the
maintainers of these packages so they can upload GHC7-compatible
versions of the packages onto Hackage?
Thanks very much for your efforts!
I think the best way to proceed for you is to put your changes in
Scion on github in a fork from mine, so then I can pull them in when
everything is ok.
