I wonder how much pain will there be when Haskell 2011 comes out.
Some packages will depend on haskell2010, and others on
haskell2011.  Will they integrate and compile fine?

If haskell2010 is a metapackage that says

  Depends: base == X.Y.*

and haskell2011 is another metapackage that says

  Depends: base == Z.W.*

then I think we're going to have big problems.  Sorry if this is
a resolved issue. :)
