Sorry for the followup, but I forgot about one other important reason
(probably the real reason) for the nullC case in bindIteratee. Note
what happens in the regular case: the iteratee is run, and if it's in
a completed state, the result is passed to the bound function (in the
"m_done" line), whic
Hi Sergey,
iteratee (the package) uses a null chunk to signify that no further
stream data is available within the iteratee, that is, at some point
the stream has been entirely consumed. Therefore, if any of the
composed iteratees haven't run to completion, they need to get more
data from an enum

I have used it a little and it worked quite nicely.
One thing that to look out for though is that it first checks for
modules from the current directory down -- so running it in somewhere

Hi community, hi John. I find myself reading bindIteratee[1] function
for a several days.. there is something that keeps me away from
completely understanding of the concept. The most noticeble thing is
\nullC\ guard in the definition. To demonstate the consequences of
this solution, let me define

I'll only claim it's a fairly breezy read for people familiar with

You can still use unqualified imports

Oh, ok, I guess I can do that too:

I also think it would be really good to have some documentation that explains
the type system and how to do neat things with it in terms that a reasonably
competent haskell / ML programmer could understand.
I played around with Ur/Web about a year ago and was able to make a simple
application,

It'd also be interesting to know what you missed in Haskell web development
so that you needed to build a new language inspired from it.

Hi everyone,
I'm working for Standard Chartered, based in New York (currently
though, I'm in Singapore).
You can reach me on this email.

First, I apologize in advance if this post is deemed off-topic. It's
about Ur/Web, a statically typed, pure functional programming languages
that is much influenced by Haskell. For instance, Ur/Web includes
monadic IO and type classes.

It seems one batch of builds was broken due to some failure in downloading
the package index. I've re-run it.

Don isn't working at Galois anymore. I guess his new email address is
simple to find but I gave it to Wren privately.
But I guess the sloth signal works fine too.

Just post something on Stack Overflow, throw in a line about how
inefficient Haskell is compared with Java. It's like his bat signal.
