Marius Gedminas f91b28ef23 Fix safe_eval() of set literals ... There was code to support set literals (on Python 2.7 and newer), but it was buggy: SAFE_NODES.union() doesn't modify SAFE_NODES in place, instead it returns a new set object that is then silently discarded. I added a unit test and fixed the code. I also changed the version check to use sys.version_tuple instead of a string comparison, for consistency with the subsequent Python 3.4 version check that I added in the previous commit.		2015-09-11 09:41:05 +03:00
