Lintian checks d/control in the source package. All of the entries look like:

Description: ${haskell:ShortDescription}${haskell:ShortBlurb}
 ${haskell:LongDescription}
 .
 ${haskell:Blurb}

You are right. The variable is not handled at all. The current Lintian
check does not work for Haskell packages.

Checking the source packages, as we currently do, has the advantage
that no built packages need be present. Lintian can run separately on
*.dsc, *.deb and *.changes, and we prefer to run on source packages
whenever possible. That does not work when variables are used, and
should perhaps be changed for all of Lintian.

A hybrid option would be to check the installation packages second, if
present, and suppress any tags not actually warranted.

This is a great bug and will require some thinking.

Kind regards
Felix Lechner
