I don't think that's quite the case -- there is a company that
employs several of the primary Twisted hackers, but I don't think
they get paid to work on Twisted during work hours. There are other
related projects that they do work on during work hours: the Divmod
projects.
On the other hand Twisted recently (after the transition we're
discussing) started soliciting donations from companies that use
Twisted and I think they paid one programmer a few times to work on
it. I'm not sure of the details.
it's not clear to me what makes Haskell suited to testing when the
whole point is compile-time rigor.
People tend to think of compile-time checking and testing as
alternatives, but that's crazy -- they're complements. If you have a
really good type-checking system and a purely functional language
then you can rule out vast swathes of the space of possible
influences on the behavior of the code under test. This doesn't
eliminate the need for testing (if it did it would be a proof of
correctness), but it does make it much easier to figure out what
inputs you need to test, because the space of inputs that can
possibly have any effect at runtime is so much smaller.
Hm, this is interesting, googling for "Haskell unit testing" yields a
tutorial by Leif Frenzel, the author of the Eclipse Darcs plugin:

And what's this? It turns out that rumors of the Eclipse Darcs
plugin's death have been greatly exaggerated! In an earlier message,

Also, when was the last time EclipseDarcs was updated? Is it still
alive? Hmm, the domain (eclipsedarcs.org) appears to have lapsed
and the SourceForge project shows no major activity in 2 years.
Ouch. (That might be a project worth reviving by somebody, but I
personally don't use Eclipse so I have no idea if anyone actually
cares.)
And yet I now see:

Oh, that is a small update and it is a year ago. Hm. I'll write to
Leif Frenzel to ask him what's the status of the Eclipse Darcs Plugin.
