Re: [Haskell-cafe] Question about Newtype op() function arguments.

2013-06-12 Thread David Banas
Ah, so is the idea, then, to use *op()* when `n` wasn't actually constructed formally, but rather assembled by the user, so as to match the type of the accessor function normally supplied as the argument to the constructor? On 6/7/2013 4:51 PM, Tom Ellis wrote: On Fri, Jun 07, 2013 at

Hello, everyone. I am looking for packages on hackage which use MVars extensively. Those which create plenty of MVars -- not just one or two for conditional synchronization or to keep track of a value throughout the program. My purpose is to analyze usage patterns of MVars. Does anybody have any

[Haskell-cafe] Testing invasive proposals with Hackager

2013-06-12 Thread Niklas Hambüchen
In many discussions we make guesses about how much code proposals like Functor = Monad would break. You can use https://github.com/dterei/Hackager to build all of Hackage (preferably in a VM). Of course many packages have external dependencies, so I'd like to share the following list of packages
