Out of curiosity, what is the rationale for allowing programs to infer
certain types, but not for the (inferred) type to be declared?

That's the type that's needed; the fact that you need an extension for
GHC to allow you

Suppose I have a big list of integers and I like to find the first two

One approach is to put the numbers in the map as I read them and each

I've got a piece of code that looks like this:

So my question is: what's an appropriate Haskell mechanism for building
code that is OS / arch / distro specific? It's not like I have autoconf

Well, for sure you can in define that in .cabal file:
if !os(windows)
CC-Options: -DWINDOWS
or something. See:

That's interesting. But are there standard values for those functions? I'm
guessing not, seeing a how they're String and not an ADT.

Note also that typeclasses are open, so ghc is not allowed to say that there is
no instance of Num for lists there; it will happily infer a type which requires
such an instance, and only when it needs to firm down to concrete types at some
point will it notice that there's no such instance in

I'm pleased to announce a new release of rss2irc, the software behind
hackagebot on #haskell. rss2irc is an IRC bot that polls an RSS or Atom feed
and announces updates to an IRC channel, with options for customizing output

Thanks for the exhaustive answer.

That's ok.
Windows certificate and macos X certificate are stored in a reliably
discoverable place. That openssl provide no way to get to it is a
different story and one reason to have tls.

I'm using netwire to build a game; one of the things the player can do is
move around using WASD. I want to use key *events* as the 'basis' of my
wires, not the entire state vector of the keyboard so that, for example, a
press event on D increments the velocity by (200, 0) and a release event
