I'd like to remind you that the Haskell98 report explicitly allows
recursive modules

However, it's a real pity that Hugs doesn't support them at all and that
you have to take extra pains with .boot-files to get them in GHC.
Recursive modules are the lazy evaluation of modules and "One should not
obstruct access to such a vital tool". I want recursive modules for free!
