Comment (by sjakobi):

 Replying to [comment:4 ekmett]:
 > I'm personally weakly against this proposal as names are very much not
 taken by `Prelude` lightly.

 To be clear, the issue is that the newly exposed `readMaybe` and
 `readEither` names could clash with pre-existing definitions that use the
 same names, right?

 > That said, this belongs as a `libraries@` mailing list proposal at this
 stage, rather than as a ticket here. If clear consensus arises from the
 `libraries@` proposal, ''then'' this would become the correct venue to put
 the feet of the core libraries committee to the fire to get it
 implemented.

 Actually I wanted to send this proposal directly to the libraries mailing
 list, but then decided otherwise after reading
 [https://wiki.haskell.org/Library_submissions#Guide_to_proposers this
 "guide for proposers"]. If that guide is out of date, it would be great if
 someone could update it to reflect the current practice.

 I'll write the email in a few days once I'm back from Christmas holidays.
 Would a discussion period of 4 weeks be appropriate?
