Hi John,
I don't know if this is useful for you, but these are instances of
Cofunctor's comap. For example if we use TypeCompose package we have:
rebox f = unFlip . cofmap f . Flip
The rest are also Cofunctors. There are a few options. You can either
specify instances or use type combinators

The important point here is that the recvFrom calls in
Network.Socket[1] don't block.
Yes, this is the answer. Network.Socket.socket calls
System.Posix.Internals.setNonBlockingFD to set socket non
So that's why it doesn't work on Windows, I think I should find some
way to make a socket unblocking after its creation.
Unfortunally this way seems to be wrong. Error codes for winsockets
and BSD-sockets are different.

Hello, I have a problem with building multithreaded UDP server. If
main thread is waiting for new request in recvFrom all other threads
are blocked too. I've checked every variant with

In that case, you need to have the RTS manage sleeping your thread for
you. You should make the socket non-blocking and handle the EAGAIN and
EWOULDBLOCK
Very clear tutorial indeed. But why isn't propCC shown as Pierce's
Law? And Excluded middle is proven on such basis.

Hi, thanks for proposal,
Why questions connected with converting are considered only?
The library i18n should give a number of other services such as
normalization, comparison, sorting, etc.
Furthermore it's not so easy to keep such library up to date.
Why simply do not make a bindings to IBM ICU
If you also read the rest of that thread, you'll see that with a recent
GHC HEAD, you should be able to avoid the need for the Teq witness.
