So I was trying to compile lambdabot with cabal-install. Lambdabot uses Template Haskell for generating some boilerplate, and it was a failed dependency. Template Haskell uses packedstring for... something... and packedstring was a failed dependency: Data/PackedString.hs:83:7: Could not find module `Data.Data': it is a member of package base, which is hidden
Now this is a problem, but it's not the problem I am interested in. I am interested in: why is template-haskell using packedstring? Wasn't packedstring obsoleted years ago?
Yes. The question is if one should break the TH api just to remove this deprecated dependency. Especially when it is slated to be replaced with an improved unicode packed string type in the future. So either we break it once, or twice. Duncan
