Comment (by nomeata):

 >  I expect the expression to be evaluated as the leading expression in an
 interactive interpreter session.

 Do you mean that the expression should be evaluated, the result printed,
 and then you’d end up at the GHCi prompt?

 I would rather expect `ghci -e` to simply behave like `ghc -e`. Note that
 python and perl will either evaluate an expression from the command line
 *or* give you the REPL loop.
