[Haskell-cafe] Is SmallCheck maintained?

2011-11-14 Thread Roman Cheplyaka
Hi Cafe, Does anyone currently work on Test.SmallCheck? I see the following problems: 1. SC doesn't have a repository, issue tracker etc. 2. It is not integrated with popular test frameworks 3. API should be better documented I'm willing to work on the above problems, but wanted to check first

2011-11-14 Thread Ertugrul Soeylemez
Hello everybody, it's finally done. I have just released Netwire 2.0.0, which is a complete rewrite from scratch. It has been generalized to arbitrary automata with inhibition, so FRP is now just a special use case. First of all the top module is now: import Control.Wire Wire is now an ar

Re: [Haskell-cafe] Do type classes have a partial order?

2011-11-14 Thread Ling Yang
It seems like you would, going by semantics of System F, where types with type variables name a certain subset of types, => constraints further restrict the types of the same "shape" (are they an independent kind of restriction?), so typeclass declarations with/without => specify a partial order o

[Haskell-cafe] Do type classes have a partial order?

Is there a partial order on Haskell type classes?If so, does it induce any quasi-order relation on types named in the instances?In the example below types C and D have the same operation fThanks,Patdata C = C deriving Showdata D = D deriving Showclass A t where f::t->t f t = t instance A C whereins
