Hmm, currently, it runs after type analysis:
_check_c_declarations,
AnalyseExpressionsTransform(self),
RemoveUnreachableCode(self),
This /may/ make a difference, considering that there may be declarations in
the dead code that may have an impact on the remaining code.
However, I would prefer running the dead code removal as early as possible,
even before analysing the declarations. If users rely on dead code making
live code work, I'd consider that a bug. That would also simplify the
removal operation, as the tree tends to be a lot simpler in earlier stages
(e.g. before optimisations, WithTransform, etc.).
