Thank you for clarification. Yeah, I think I saw it on GHC Trac too. It
is very neat! But what prevents it from being useful for real software?
 I often use anansi ( http://hackage.haskell.org/package/anansi ) when
prototyping new projects, so that I can write multiple modules in one
file. (One .anansi file generates a number of .hs files.) But it is an
ugly workaround at best.

Yuras.
