@sobolevn, I think we should start with adding tests. I'll be adding tests to this, but it would be great if you could add some as well to make sure I don't miss any edge cases etc.

Also, @sobolevn if you have a better idea than what I've done on how to make this optional i.e. only have this functionality if hypothesis is installed, that'd be great.
