Abstract

Over the last decade, step-indices have been widely used for the
construction of operationally-based logical relations in the presence
of various kinds of recursion. We first give an argument that
step-indices, or something like them, seem to be required for defining
realizability relations between high-level source languages and
low-level targets, in the case that the low-level allows egregiously
intensional operations such as reflection or comparison of code
pointers. We then show how, much to our annoyance, step-indices also
seem to prevent us from exploiting such operations as aggressively as
we would like in proving program transformations.
