Okay - to put a concrete proposal on this:

1) Include dlist-0.6, which would have the additions that Sean L. has proposed
2) Include scientific as package
3) Include an aeson that is updated to use the above two packages (and won't use blaze-builder)

Sean - do you have a time frame for such changes?
Bas - do you feel the API of scientific is solid enough to go into the platform? Are you willing to commit to the stability needs of the platform(*)
Bryan - are you ready to turn out an aeson version that uses the above once they are out?

Everyone else - After all the conversations, do we feel the rough consensus is to go ahead with these. In particular the changes that Sean proposed for dlist, and the inclusion of scientific.

I realize this is Thanksgiving week in the U.S. - but let's hope we can come to a close on this by next Tuesday - Dec 3rd. Preferably sooner!

(*): Meaning, the package would remain backward compatible for a few revs with ample deprecation time before altering APIs that would break code -- even through major version number changes.
