Re: Deprecate Foldable for Either

The issue is that if a "grumpy person" imports any library which uses the Prelude (I have a feeling they might), then under the open world assumption they will get the instances that to them are broken. If we can get a warning then those of us who find the instances dangerous might be more willing to live and let live. Tom

Same here.

I wasn't that happy with the FTP proposal when it first came up due to potential confusions (primarily due to naming conventions like "length"), but now that it's done we shouldn't go back.

We should have at least compiler warnings for those who care.
