An extension of the simply-typed -calculus, allowing iteration and case reasoning over terms of functional types that arise when using higher order abstract syntax, has recently been introduced by Joëlle Despeyroux, Frank Pfenning and Carsten Sch¨1rmann. This thorny mixing is achieved thanks to the help of the operator ` " of modal logic S4. Here we give a new presentation of their system, with reduction rules, instead of evaluation judgments, that compute the canonical forms of terms. Our...
