Languages must be tidy, when possible. It's often better to not have
a feature that having a dirty one.
I think in this case, it's more about cleaning up and polishing, than
adding "warts".
The big danger is, that this may require incompatible language changes,
which won't be possible anymore after D2. D3? Anyone who talks about D3
must be kidding.
So D3 won't ever appear? At least in many open source projects the
final released is tagged one to two weeks before the final release.
Distributions have then time to repackage the release. Meanwhile, the
core developers are already enthusiastically implementing wild new
features after a long feature freeze.
It's similar kind of tick-tock as Intel has with their CPU line (1
smaller process -> 2 improved core -> goto 1). In successful software
projects they have alpha/beta period, feature freeze, stabilization
period, release, new alpha/beta period etc. Concurrently new bugfix
releases come out just like with D. I haven't heard of new features
lately so D2 must be stabilizing now.
According to development stages you provided, D2 is currently in
alpha/beta period. Feature freeze will follow once TDPL is released
(around March, 2010). Stabilization and release is even further, and D3
is sooo far away it's hardly imagineable we will see any signs of it in
a foreseeable future :)
Yes, that's about right. Let's get an estimate about stablisation:
There are 1400 open bugs (DMD+Phobos), which are currently being fixed
at the rate of 50/month.
Historically, new bugs have been found at the rate of 66/month.
Since D2 began, 50% of the open bugs have been D2-only. So, 50% of the
bugs have been related to new features.
Which would suggest that even if the bug rate halves when after the
feature freeze, it'll be about 5 years until the bug count drops to
zero... :-(
Actually, I don't think it's that bad, since some of the most important
structural compiler bugs have been fixed, which should greatly reduce
the rate that new bugs are found.
Even so, I'd recommend at least two years of bug-fixes and library
development (and toolchain issues), before we even think about more
features.
