Recently I had the need to filter objects based on whether they're picklable
or not:


I'm not sure what's a good way to check for a specific object whether it's

led me to think: Maybe we should have an `Unpicklable` abstract base class
in the `collections` module? Then various unpicklable classes, like locks,
files or widgets, could inherit from this class to signify that they cannot
be pickled.

What do you think?
