Comment(by simonpj):

 Oh, sorry, I meant that it should say
 {{{
 what.hs:1:1: The function `main' is not defined in module `Main'
 }}}
 If instead it was
 {{{
 module What2 where
 foo = True
 }}}
 and you said
 {{{
 ght -e bar What2.hs
 }}}
 then a "not in scope" message would make more sense.  But in the common
 case of 'main' (which is what happens with `runghc`), the `No main in
 Main` message is better
