Comment (by osa1):

 I think there's another bug here which is that `let x = ...` and `x = ...`
 are supposed to be the same thing in GHCi, but they're currently not. I
 vaguely remember the ticket that requested supporting `x = ...` syntax in
 GHCi (without the `let`), but I don't remember how it was implemented. I
 guess there's a bug there and perhaps we should track it in another
 ticket.
