Why do you catch TypeError exception?

comment:4 Changed 3 years ago by tscrim

Because that is what happens when you pass unexpected keyword arguments as noted in the ticket description. Admittedly, the proposed fix is a slight hack, but IIRC, there were some issues with adding a compact argument to all possible inputs and this is not an unpythonic solution.
