{Rewriting \TeX\ today}
{\TeX82 was written forty years ago. The constrained memory resources as
well as portability concerns and compiler limitations of that time have
set strict bounds to the original implementation. As some consequences
of these bounds \TeX82 features hand-written dynamic memory management,
ubiquitous use of global variables, and manual string management.

In this talk, I will discuss the joys and challenges of rewriting \TeX82
today without these limitations.}
