I was working on something similar to a thing that could be used to
answer this question, so I made it into a thing that could be used to
answer this question. See here:

In your case, you can call paths.get_paths(function() return
my_weak_table[my_key] end) to get a list of paths from a few starting
points. It takes a function like this to avoid creating extra
references to the thing, which would then be found by get_paths,
adding some noise to the output.
