This paper extends the recent work [CMT00] on the opera- tional semantics and type system for a core language, called MiniMLBNrefBN which exploits the notion of closed type (see also [MTBS99]) to safely combine imperative and multi-stage programming. The main novelties are the identification of a larger set of closed types and the addition of a binder for useless variables. The resulting language is a conservative extension of MiniMLref, a simple imperative subset of SML.
