Comment(by simonmar):
Thanks for the patch. One thing I'd be concerned about with saving the
entire GHC session across `:reload` is space leaks - we're careful to
discard modules in `:reload` to avoid keeping two copies of the code in
memory at the same time.
Also I think this ticket is asking for something a bit different - keeping
the previous bindings in a module until they are replaced by successfully
typechecked new code (if I understand correctly) so that the old code can
still be inspected after a type error.
