I think it's a feature, not a bug. When dealing with monads that
provide nice[1] implementations of `fail`, you can (ab)use this to
avoid writing a bunch of case expressions. I remember

Hi Myles,
These sound like two solid features, and I'd be happy to merge in code to

I've received a number of reports of a broken zlib 0.5.3.2 (and

As a temporary workaround, I've released a new version of

later). Once a new patched version is rele

Actually, Persistent is fully usable without any special syntax, DSLs,

Seems to work perfectly for me. The statement you're expecting to be

closes its socket. If I connect it to Warp, this takes about 30

Hideyuki Tanaka alerted me[1] to a memory leak in conduit. Long story

Hi all,
I'm wondering if there are still active users out there of

then, my development efforts have gone almost exclusively there. At
this point, I'm not longer actively using http-enumerator on any of my

I agree that this behavior is non-intuitive, but still believe it's
the necessary approach. The short answer to why it's happening is that
there's no exit path in the yield version of the function. To
understand why, let's expand the code a little bit. Realizing that
liftIO = lift . liftIO
an
yield/await would be a good solution to the problem?

Hi all,
I'm just about ready to make the 0.5 release of conduit. And as usual,
I'm running up against the hardest thing in programming: naming
things.
Here's the crux of the matter: in older versions of conduit, functions
would have a type signature of Source, Sink, or Conduit. For example:

Hi Kashyap,
I'm not sure if it will solve the problem, but I ran across a tool[1]
the other day that bundles up applications with all of the libraries
and other resources they need. I wouldn't be surprised if, with this,
you can get your code to run on OpenShift.

Hi all,
A quick search indicates that this problem has come up in the past,
but I haven't seen any solutions yet. I'm working on the next
Persistent release, and one of the changes is that the included
sqlite3 C library has been updated (I believe that's the trigger
here). I can compile programs a

Hi all,
I've been working with Aristid on an enhancement to resourcet[1]. Please
see the issue for more details, this email isn't about that change.
Instead, now that we're looking at a new breaking release, I was wondering
if anyone had ideas of something they thought should be changed in
resourc
