I would like to formally propose that Monad become a subclass of
Applicative
A lot of code would break because of this change, but all problems should be
reported at compile time, and are easy to fix. In
Maybe I'm missing something - but shouldn't the code listening on the
Handle already be in it's own thread?
The general recipe is:
1. Bind a socket to port
2. Call Network.accept, then take the resultant Handle, call forkIO
with the TLS actions and the resultant handle. Go back to 1.
So even
Is there a discussion deadline, if this now a libraries proposal?
For something like this, you might want to advertise the discussion on
Plane Haskell, and the -cafe to get adequate discussion, as it seems
sure to break quite a few things. And reddit, although I consider that

Hi all,
I read the paper about the new ghc7 event handling IO manager goodies.
This is all very exciting stuff. I didn't know GHC's RTS had these
smart async-IO facilities.
The paper pointed me at
One nice thing that WebSharp does is that you can annotate types and
functions and then use them on both sides - on the client and on the
server - almost transparently.
Then you can write common utility functions once, but you only
maintain one code-base and one build workflow.
I haven't used it
I only have some surface level questions/comments -
What existing packages is this similar to? How is it different from
any previous work in the area?
Also, likes looks like you don't need the 'Monad m' constraint on your
various Monad and Functor instances in Data.Iteration.Types, which I
think
compliant?
I haven't experimented too much with this sort of thing, since Cabal
defaults to the Haskell '98 language, and that's how I install most
things.
Thanks for your response,

Hi Sebastian,
I imagine that many of the instances are defined in the module that
defines the data type. For example, the STM instance is defined in the
same module as the STM type.
Are there any particular ones you're running into problems with?
Take care,
Antoine

Hi Haskell,
I've recently created the 'smallstring' package[1] and put it on
Hackage. The goal was to create a string-like type with as little
memory overhead as possible, and to have equality and comparison
operations be competitive with the native String type. The idea is
that this type would

be useful
