Significantly different? They are practically identical.

I am a Mac user and I disagree. I know several mac users who also
disagree. I remember that NeoOffice used to be much more popular than
OpenOffice.org on Mac because OOo used X11 and NeoOffice didn't, even
though it was clear that NeoOffice was not quite native. You are the
first mac user I meet that feels the way you feel. I have met quite a
few mac users who don't share your views.
X11 apps look like crap. And I disagree with the "uncanny valley" thing
because *native* OS X apps can look quite different. There isn't a
single uniform look for native OS X apps but at least two. Looking at
the screen shots on the wxHaskell website, if I saw that on my Mac, it
wouldn't cross my mind that it isn't native.
> Well yes, but then all macs come with 2 button mice, so *shrug*.
Mine doesn't and every mac I've seen doesn't, so don't dismiss me like
that, it's very rude. Also, in macs the command key is used a lot, you
can't just throw it away and "shrug" like you just did.

Yep, very imperative, but it works.
At least gtk2hs is easiest way to build Haskell GUI program.

Thanks.
It's hard to argue with "it works". I'd rather have something that works
on two platforms than something that fails on three platforms :-) Have
you any experience with wxHaskell? Do you find it harder to use? Or is
it more buggy?
Daniel.

It uses the applicative functor (Control.Applicative) instance for
lists, just as "fmap return" uses the monad instance. Both work out
to the same thing.

In the list monad, "collect" means "concatenate".

Hi all,
I'm looking for a Parsec tutorial that can get me started in writing a
simple SQL parser.
I can't seem to find a lot using Google. Does anyone have some
resources that could be helpful?
Thanks a lot,
Patrick

We can't solve problems by using the same kind of thinking we used when we
created them.
