I recently tried using ShareableList (from the multiprocessing library) and encountered a shaky behaviour. This was due to me feeding a float instead of an it, leading to pseudo-random memory addresses.
To prevent others from having the same problem, I added type checking on reading to have a behaviour more similar to what list do (errors on non-int indicies).
I'm not sure it need a issue as the fix is really minor.
Have a good day
