Abstract
We present a call-by-value effectful lambda calculus with capabilities, with a comonad that filters out pure expressions. We give a categorical semantics for it and show the soundness of substitution. We give an equational theory for our calculus and prove soundness for it. Finally, we give a translation from the pure call-by-value lambda calculus to our calculus, and show that it preserves the equational theory.
