----------------------------+-----------------------------------------------
 When GHC is run in expression-evaluation mode (i.e. with the "-e" flag)
 and the expression does not compile, GHC correctly prints an error
 message, but then exits with exit status 0. For example:

 {{{
 $ ghc -e foo

 <interactive>:1:1: Not in scope: `foo'
 $ echo $?
 0
 }}}

 This is inconvenient for automated scripts that call GHC.
