We introduce a type and effect system, for an imperative object calculus, which infers \emph{sharing} possibly introduced by the evaluation of an expression. Sharing is directly represented at the syntactic level as a relation among free variables, thanks to the fact that the calculus is \emph{pure}. That is, imperative features are modeled by just rewriting source code terms. We consider both standard variables and \emph{affine} variables, which can occur at most once in their scope. The latter are used as {temporary} references, to ``move'' a \emph{capsule} (an isolated portion of store) to another location in the store. The sharing effects inferred by the type system are very expressive, and generalize notions introduced in literature by type modifiers.
