Intensional lambda-calculus adds intensional combinators to lambda-calculus to facilitate analysis. In particular, they are used to factorise data structures and programs into their components, which can be used to convert abstractions into combinators. This paper shows how to type an intensional lambda-calculus using no more than the types of System F. Even the quotation function used to access program syntax can be defined and typed, as can its inverse: the calculus supports typed self-quotation. Thus, one may freely alternate between program analysis and program execution. Proofs of all results have been verified in Coq.
