Not a single name, but I believe
liftA2 mplus
is the same function, and much shorter (and more general). It uses the
Applicative instance for (a -). Of course, it also works with liftM2.

Hello all,
Yesterday I uploaded a new package on Hackage called generic-deepseq. It
implements the 'deepseq' function generically using the new GHC.Generics
framework as found in GHC = 7.2. It can be used as a replacement for
the deepseq package.
Given that hackage is currently down, here is an

Well, the command-line tools are now available as a standalone package[1]
separate from Xcode[2], so Apple's taken notice of and responded positively to
large efforts like Homebrew and MacRuby. With that in mind, I don't think it's
unreasonable to think this support also applies to other users
Hello Felipe,
If we have separate directories, then you can build-depends:
own-package. This means that on the test suite's build-depends you
need to list only the dependencies that the test-suite needs, not
every dependency. Also, you don't need to constrain the version of
any duplicated

As has been mentioned, it's already possible to override Gatekeeper on a

again. Is it unreasonable for your users to open it that way once? As for

In fact, since Gatekeeper, by design, can only quarantine applications acquired
through the App Store or a download (or any other method which applies the
quarantine flag), it may be entirely irrelevant for you depending on how you
distribute. Applications on physical media are exempt, source

I do think it's better to integrate this into the deepseq package (and
thus removing the default implementation of rnf). Otherwise we end up
with two ways of evaluating values to normal form.
I agree with this, and I guess many people are
