1: Aliasing, where C is not the language you want to start with. If
you think that you understand this, you haven't exen started to get to
grips with the issues. Seriously.


2: The syntactic and semantic complexity of the loop constructions,
which means that you HAVE to rely on heuristics as to what actual
programmes write and not what the language allows them to.
