Yes, the problem is a space leak in Haddock. On a 32 bit system it
takes up to 700MB of RAM. You should probably disable haddock for
now. David Waern is working on a fix, but I don't know how long it'll
take him.

There's a whole bunch of other problems with lazy network IO. The big
problem is that you cannot detect when your stream ends since that
will happen inside unsafeInterleaveIO which is invisible from inside
pure code. You also have no guarantee that the lazy code actually
consumes code enough.

If you have lots of local changes (e.g. the sorts of long-running branch
that gives darcs 1 problems), then you need to use merge. If you use
rebase then you might end up with lots of conflicts to manually resolve.
Using merge gives you automatic merge commits, If you think these are

you don't use local branches?

Are you advocating for ease of use by new developers or for existing

Darcs already. Library patches still have to be recorded separately,

I'm was wondering how most people work during when designing a functional
program. Do you create data structures/types first? Do you work from some
type
signatures?
As others have mentioned: both. But there's a third thing that

that ?).

In fact, the docs on hackage are interlinked nicely. That is, for
packages for which the documentation builds.
