It is a partial function that does not provide a call stack, and it's very slow too.

I propose deprecating Prelude.read. Adding deprecation should not break anything substantial because Hackage rejects -Werror (application code using -Werror is likely to experience a lot more breakage anyway, and I'd say it's their fault if it fails to build due to a use of read along with -Werror).

Of course those who still want to use Prelude.read can totally ignore warnings. I believe this proposal is not that controversial.
