impl<'a> TryFromSexp for &'a mut Rcomplex

Safety note (aliasing)

This impl can produce aliased &mut references if the same R object is passed to multiple mutable parameters. The caller (generated wrapper) rejects overlapping native mutable/shared borrows before conversion. Direct conversion callers must enforce this borrowing contract themselves.
