[Haskell-cafe] Cyclic Inclusions

Hi, I have a question about cyclic inclusions. It appears in the Haskell 98 report that mutually recursive modules are allowed, however GHC complains at any Haskell project that has cyclic inclusions (implicit or explicit). Am I right in thinking that this is a GHC limitation? http://www.haskell.org/onlinereport/modules.html Kind regards, Chris.
