I think that might be a little overoptimistic. The fundamental problem
with darcs is that nobody understands the semantics. Until there's a
proper semantics that people can understand, I don't think the problems
with merging and conflicts can really be fixed. Even if the semantics
can be nailed down, there are some difficult UI issues to solve.
We're not moving to v2 patches right now because we have enough
experience with v1 to know how to avoid the bugs, but I'm less sure we
could avoid the bugs in v2. To the darcs folk: do you think this is

Opinion on whether we should switch seems to be pretty evenly split at
the moment (personally I'm agnostic). Besides that, the main stumbling
block is that the GHC tree consists of about 20 repos, with different
maintainers, so making it so that a GHC developer only needs to use one
VC tool could be tricky.
