Hi All I've been doing some work on generalising categories, basically so the composition operator (.) works for not just functions, but things like tuples of functions, whilst still retaining type inference. Control.Category is a bit too restrictive for such instances. You can see the details in my blog post here: https://clintonmeadprogramming.wordpress.com/2016/02/16/generalising-categor... Any comments appreciated, I hope people find it interesting. Also, a quick plug, I'm looking for work, so if there's any Haskell (and/or functional programing) work around Sydney, Australia going I'd be interested. :-) If people really think this is useful, tell me, and I'll try to put it up as a package. Alternatively, if it's already been done, I'd appreciate a pointer in that direction. Regards, Clinton Mead
