Hi,
Hoogle is definitely not deprecated. The reason you can't yet search
all packages simultaneously is that it consumes too many resources -
the number of Haskell packages exploded at a time when I wasn't able
to spend enough time to allow Hoogle to keep up. It's definitely
something on the todo
Hoogle has returned to live, thanks to the efforts to the new
haskell.org admins.

Hi,
Seriously, cmdargs is *brilliant*. It's also magic (to me).
Not only to you in fact it is black magic since it uses unsafePerformIO :(

Hi Jason,
I believe the original purpose of IsString was to enable writing of

Hi,
It probably helps to know some of the history, as it explains a lot of
what you see today. Hoogle was written first (about 5 years ago now),
before there was hackage (so it doesn't search hackage), and with an
