  abstract = {Haskell is a great language for writing and supporting embedded Domain Specific Languages (DSLs). Some form of observable sharing is often a critical capability for allowing so-called deep DSLs to be compiled and processed. In this paper, we describe and explore uses of an IO function for reification which allows direct observation of sharing.}
