Hi, I only got positive feedback, so I’ll merge this in a few days. Cheers, Joachim Am Donnerstag, dem 29.06.2023 um 08:20 +0200 schrieb Joachim Breitner:
Dear committee,
Krzysztof Gogolewski in https://github.com/ghc-proposals/ghc-proposals/pull/596 amends the sized literals proposal so that GHC uses the syntax 42#Int8 instead of (intToInt8# 42#) in the stock derived Show instances for data types with sized unboxed numbers.
Implementation is also ready.
Now that we have a syntax for these literals it’s clear that we want to use them in the show instances.
There is no risk of breaking Show-Read-roundtripping, as Read instances cannot be derived (at the moment).
This is a change in behavior of Show, so we should think for a moment how this affects stability. But none of the libraries in libraries/, in particularly not base, are affected by this change, according to Krzysztof.
So I recommend to accept this.
Cheers, Joachim
