Yes, I know that I can evaluate line by line, but that can get boring pretty
fast. When doing interactive evaluation sometimes one wants to evaluate a
group of statements and do multiple bindings, so yeah, I guess I have to do it
that way then.

The hsc3 mode in emacs also has multiline evaluation, that was not the issue,
the issue was evaluating expressions that use the indentation rules (so no { }
in do blocks, etc ).
