so why hasn't this been released yet? it's been over a year with a known showstopper bug and a known fix? this is crazy

I'm not sure why older GHCs are unable to infer the types for the tests I've added, since the types should all be trivially known (Text and Char).

Yeah I've been working on rewriting the C to avoid going via memmem, and removing the twoway_memmem would significantly reduce the amount of code to maintain. I would guess there...

I'll try and find some time to write a Haskell only version, and then we can think about making a faster C one later. I wonder if it's worth having...

Yeah as far as I know unless you're directly producing something Rep like and then consuming it GHC should go a good job deforesting the intermediate structure, but if you...

Another example from a channel with very little activity after switching from #ghc

https://github.com/commercialhaskell/stackage/pull/4560 :) Currently the nightly doesn't contain any amazonka libs but once it does this should appear too.

This issue got me thinking, and asking questions on IRC, and it looks like the [wcwidth](https://hackage.haskell.org/package/wcwidth-0.0.2/docs/Data-Char-WCWidth.html) package _might_ be useful to start a fix, but this really feels like something...

Also the text-icu package has some support for breaking text into glyphs: https://hackage.haskell.org/package/text-icu-0.8.0.4/docs/Data-Text-ICU-Break.html

I'll see what I can do tonight.
