Yes, it is helpful, and it can be quite feasible to implement for local
variables.  But it's a lot harder for components of records on the heap,
accesses through complicated chains of pointers.  In most of the
programs *I* write (compilers and related tools), most of the data is
sitting in heap-allocated records, which is why I would like to have
run-time detection, in case the compile-time detection fails.
