That's great, but primitive is not a GHC boot library, and it depends on transformers, ..., so I'm still stuck copying code into containers (the copy I made from discrimination falls back to MutableArray#). On Jun 22, 2016 8:58 PM, "Edward Kmett" wrote:

I've been talking to Dan Doel about adding them to `primitive`, possibly w/ backwards compatibility wrappers.

The only user-friendly wrappers I can find for SmallArray# and SmallMutableArray# are in Data.Discrimination.Internal.SmallArray in the discrimination package. What are the chances that we could get something like that in the array package, or possibly some other GHC boot package? I can't use discrimination in containers!

From a core libraries perspective it'd be good to have these in one place. Right now we have them in primitive.

If we're going to start duplicating *that* much code, it seems it'd be worth incurring the dependency, which would get David his transformers dependency in turn. -Edward On Sat, Jun 25, 2016 at 9:46 PM, wren romano wrote:

Depending on what you have in mind, I do have some (relatively) user-friendly wrappers in the unreleased new version of bytestring-trie. I mention because I'm planning on moving those wrappers into containers (and making them public so bytestirng-trie can reused them) once I get a chance to add the AMT implementation for IntMap this autumn.
