Re: Proposal: Deprecate decodeUtf8

Or should it be changed - decodeUtf8 = decodeUtf8With strictDecode + decodeUtf8 = decodeUtf8With lenientDecode

I propose to add a deprecation pragma to the partial function Data.Text.decodeUtf8.

I see checks or decoding failure accidentally omitted from production code every week. I claim decodeUtf8 to be *the* most abused partial function in the current Haskell ecosystem (with `head` and `tail` at least everybody knows they should feel bad when typing them down).

decodeUtf8' with custom error message is a better solution in all cases I have seen and can come up with.

I therefore propose:

* Add deprecation pragma to decodeUtf8 * Do it with Text.Lazy and *16/*32 functions too * But keep them indefinitely (we don't want to break compiles)

I believe that deprecating decodeUtf8 will result in lots of useful warnings across the world every day and less software crashing at runtime.

Discussion period 2 months.
