__repr__for inspected objects currently does not work because a lot of objects contain circular references (for example index <-> constraint) which leads to infinite recursion.This PR adds a fix for this by keeping track of which objects have already been visited during a call to
__repr__and returning'...'for recursive references instead of resolving them. I've shamelessly stolen the technique from the popular "attrs" library: https://github.com/python-attrs/attrs/blob/f680c5b83e65413eeb684c68ece60198015058c3/src/attr/_make.py#L1643
