teyit ignores assertRaisesRegexp

[nega0]

assertRaisesRegexp was renamed to assertRaisesRregex in Python 3.2, and is going away in 3.12. Unfortunately merely adding it to DEPRECATED_ALIASES breaks its use as a context manager

Given:

diff --git a/teyit.py b/teyit.py
index 60f87ad..5798e4c 100644
--- a/teyit.py
+++ b/teyit.py
@@ -44,6 +44,7 @@ DEPRECATED_ALIASES = {
     "assertNotAlmostEquals": "assertNotAlmostEqual",
     "assertRegexpMatches": "assertRegex",
     "assertNotRegexpMatches": "assertNotRegex",
+    "assertRaisesRegexp": "assertRaisesRegex",
 }

and:

import unittest

class foo(unittest.TestCase):
    def testBar(self):
        with self.assertRaisesRegexp(Exception, "message"):
            pass

teyit will wipe out the context manager, and fail with an indentation error:
