For inline-r we have added a revision that sets upper limit, so now hackage and stackage should both be happy. I'm not sure if any Linux distribution provides inline-r as a package but that should be normal situation for them. Next version will either set lower dependency boundary or will keep a co

I think I'm a bit late for the party. I'm speaking with the newcomer hat on, as basically I have contributed only few trivial patches. So not sure if my experience matter. Originally I was submitting patches using Trac, but then was kindly asked (IIRC by Simon Marlow) to use Phab instead. Surpris

Ok. In this case, I'm interested in main users of ghc library, as I have to make sure that they will not be broken by any changes that I'm introduce? I can take few from hackage but maybe there are ones that users care about. So I can validate my solution. -- Alexander On 22 January 2015 at 03:11

Proposal for removing transformers dependency

2015-01-21 Thread Alexander V Vershilov
Hello. I'm coming with a proposal for removing transformers dependency from ghc library. The reason for this proposal that it's not possible to build consistent environment where a modern libraries (that depend on a newer transformers or mtl-2.2) and libraries that use ghc API are used together. A
