Hi Joey,
Apologies for such a late reply. I don't know if others have replied on
-cafe; it has become too high-volume for me to follow of late. There
are several options. MissingH is one. I have accepted patches there
for a long time. Another is that now that Hackage/Cabal foster easy
That is one of the wonderful things about haskell, most languages have
a negative correlation between codesize and productivity, however with
haskell there is a strong positive correlation. You can re-use so much
that as your code base grows it becomes easier to add new features
rather than

Is this partition from Data.List?
No; it's like break but does not include the separating character in the
snd list.

I'm finding a rather unusual problem as I write haskell..
Unlike every other language I've used, large portions of my haskell code
are turning out to be general-purpose, reusable code. Fully 20% of the
haskell code I've written for git-annex is general purpose. Now, I came out
of a decade of perl

Instead of putting all of them in one package, how about you
You might find many of these on hackage in various forms already.. it
might be easier to just depend on some of those libraries.

Some quite generic monadic control functions, few of them truely unique:

Is this the same as Data.Maybe.maybeToList?

This has been added to base recently [1].

One thing I found useful when looking if a function already exists under a
different name is to use Hayoo to search for the type, i.e.:
http://holumbus.fh-wedel.de/hayoo/hayoo.html#0:(a%20-%3E%20Bool)%20-%3E%20%5Ba%5D%20-%3E%20(%5Ba%5D%2C%5Ba%5D)

There is also Hoogle, pretty equivalent I guess.
