Hi, I see that #97 applied only to PyPy2 but I see failures with PyPy3 (7.2.0) too. Changing the compatibility function to make it apply to all PyPy versions fixed it for me. ``` ====================================================================== ERROR: test_repr (importlib_metadata.tests.test_main.TestEntryPoints) ---------------------------------------------------------------------- Traceback (most recent call last): File "/var/tmp/portage/dev-python/importlib_metadata-1.1.0/work/importlib_metadata-1.1.0/importlib_metadata/tests/test_main.py", line 211, in test_repr assert 'EntryPoint' in repr(self.ep) File "<string>", line 33, in __repr__ File "<string>", line 33, in __repr__ File "<string>", line 33, in __repr__ [Previous line repeated 832 more times] File "/var/tmp/portage/dev-python/importlib_metadata-1.1.0/work/importlib_metadata-1.1.0/importlib_metadata/__init__.py", line 127, in __iter__ return iter((self.name, self)) RecursionError: maximum recursion depth exceeded ```
