I wanted some more discussion before making a formal proposal - as you point out, there's a lot to consider. Cross-posting to cafe. On 12/12/2010 19:33, Antoine Latter wrote:
Is there a discussion deadline, if this now a libraries proposal?
For something like this, you might want to advertise the discussion on Plane Haskell, and the -cafe to get adequate discussion, as it seems sure to break quite a few things. And reddit, although I consider that a less contemplative venue. Maybe other places?
Do we know of any cases where this sort of conversion will be hard to do?
This is also usually the part of the discussion where I would ask for an estimate as to how much this breaks what is published on Hackage, but I think the answer would be "a lot." If I depend on a prior version of the 'base' package, I'm guessing that I'm not insulated from this change, due to how de-sugaring happens.
Do other haskell compilers (Hugs, NHC?) use the base library? How does this change affect them?
Are there any ways to make this sort of change not break things? There has been talk about a language extensions to make this thing work out, but they have never been fleshed out, and they've always been the sort that sounded like they would have many corner cases.
I don't like breaking things, even though the new hierarchy makes a lot of sense.
