Re: Pre-Proposal: Add Validation somewhere easily accessible

I may have misread, but it seems like Errors is isomorphic to Validation. Nonetheless, I'd still support having something like Validation in the either package, as I'm certain the error messages that would result from using Errors would be atrocious, making it a non-starter for many use cases.

Lift is rather different than Validation.

Brilliant, thanks a lot! For me, having it in transformers outweighs all the benefits that a separate package may provide (especially a package as heavy as 'errors').
