[Message part 1 (text/plain, inline)]

Hi Philip,

> Since Cabal 2.2 conditional blocks support the `elif` construct [0], but our hackage importer does not currently support such expressions. This causes importing packages like `raaz` [1] to fail.
attached patch series fixes the import for `raaz` by adding support for
elif and other minor adjustments. There still is syntax we do not support,
most importantly mixed indentation, which is already documented as xfail
via a testcase. I’m adding a few more.

Could you have a look please if these make sense?

Cheers,
Lars
