There is a new version of Djinn available, with two notable
new features: Haskell data types can be defined and the
found functions are sorted (heuristically) to present the
best one first.

Yes.

Thanks, Joel

Folks,
I need some help from those of you with a FreeBSD box.
It looks like 'ulimit -n' on FreeBSD lets you have 10k+ file
descriptors open per process. FD_SETSIZE is 1024 in the system
headers, though. GHC relies on this value (see ghc/rts/Select.c).
Normally, you will get the EMFILE erro

Bulat,
How is your library licensed?
How can a process maintain internal state?
How would I use your library to code a socket reader/writer that
writes received events to the socket and propagates back anything
that is received?
The producer/consumer in front of this network client would
Thank you Bulat, makes total sense. This list is a treasure trove of
a resource.
I guess this is what happens when you go from Erlang to Haskell :-).
I'm conditioned to think of everything as a process and uses
processes for everything.
