yay, a good naming proposal! This explains what I meant by the thing
with macros - of course it cannot provide base-2.0, but it provides
something close to that base API, such as you would expect from a
version number increase.
what if the ghc 6.8 branch's base has to change enough that it needs to
be incremented to 3.1 by PVP? Or maybe that should never happen.
but, oh, the .cabal file should be changed _after_ the release of 6.10
(so that it will be accurate) (otherwise it might be >= 3.0 && < 4) so
we'll know what the version numbers are (as long as we never do a point
release of a previous GHC branch, once "3.1" has been taken by 6.10's
base) It could be "3.5"... but then that theoretical 3.1 would be
considered a valid dependency even if it contained different API changes
that broke things... so, okay
