The TILT compiler for Standard ML is type-directed and type-preserving,
that is, it makes use of and translates type information during the
phases of compilation. Unfortunately, such use of type data incurs a
significant overhead. This paper explores methods for abstractly,
conveniently, and efficiently storing and manipulating type information
in TILT. In the end, we discover that doing more work to reduce
overhead is a bad strategy for this situation.
