Here are some more example questions, perhaps not quite so far fetched.

What if I put a watch on p->f where there is a visible p, then execution
goes somewhere where p is not visible, but p still exists? For example,
suppose p is local to function foo, and foo calls non-nested function bar.

Or, I haven't placed the watch yet and first stop execution in bar. Can
I now place this watch after moving up the stack to foo's frame?

In fact, in general, many of my questions about p's being visible could
be reformulated to p's existence, which might be a more meaningful
property.
