A useful example of package coming "as standard" with GHC 6.6 is Text.Regex.

In GHC 6.4 all of Text.Regex and Text.Regex.Posix was part of the base package.

I wrote a replacement set of packages:
 regex-base providing Text.Regex.Base*
 regex-posix providing Text.Regex.Posix*
 regex-compat provided Text.Regex

The replacement Text.Regex was exactly the same API as the old Text.Regex, but
used the new regex-posix package as the lower level.

The new lower level Text.Regex.Posix was compatible with old Text.Regex.Posix
