It is, but if the packages haven't been updated for new-style exceptions by
now, they're probably effectively unmaintained. Do you want to take over
maintainership?

I don't want to take over maintainership, area of my interest is
slightly different and not covering games at all. Recently, I stumbled
at this kind of problem by myself. I wrote to maintainer, submit patch
and it's work now for new ghc.
The thing we should talk here, that cabal shouldn't even show package in
install list, that don't builds on users current compiler. This
information can be seen at hackage, but there still a lot of work is
going on new hackage, which would be more accurate continuous
integration portal.
In this situation I always get sources and correct by myself.
Maintainership policy is very controversial subject and discussed
regularly in community.

So a week into Haskell, I still seem to be not ?getting? it which is kind
of weird in my case. I came in with knowledge of a lot of functional ideas
from using them in Javascript and Python. Or at least I thought I knew
them.
5 chapters into "Learn You a Haskell", I admit it's not really sinking in
for me even after typing in and running all the examples. I acknowledge
that I don't know jack. Any ideas or exercises that might help me along?

Starting Project Euler in Haskell gave me those "hey, I remember a code example
that would help me here" moments, which lead me to looking up half-remembered
things like mapping over lists and really seeing the beauty of guards and types
in function signatures. Back in university I know the exercises were where my
real learning took place, not in reading the textbook or listening to the
lectures. And it's the same with Haskell.
Good luck,

What are the difficulties? I am a week into writing a tiny
thing, and I hope to, once I get something done, post about the
BIZARRE WORLDS OF HASKELL.
oo--JS.

You should probably start by forgetting everything you know from JS and
Python. Of course I don't mean -everything-, but if you ever end up
thinking `I did it this way in JavaScript so I'll just do the same
here', you're probably not on the right track.
As others suggested, doing some exercises is a good way to get started.
I'd like to add to this by saying that the exercises probably shouldn't
be too much out of scope until you at least finish reading LYAH. It's
quite common to see someone on this mailing list jumping in too fast
which results in very poor Haskell that is just pretty much a direct
translation from a different (often imperative) language.
I do suggest a small project once you finish reading though. It's far
easier to grasp the language if you have to look things up. More often
than not, to use someone's library will require the understanding of the
concept that it's built upon which means that you end up learning more
which is the goal here.
Good luck.
