I identified the regression, I created: http://bugs.python.org/issue28637 It's a regression caused by: https://hg.python.org/cpython/rev/223731925d06/ http://bugs.python.org/issue28082 The change added "import enum" in Lib/re.py. I propose to revert this change for now, and discuss later a solution which doesn't impact performances. It's nice to see that my work of performance was useful to catch a performance regression.
