+Subject: [PATCH] Fix test_too_many_fields with Python 3.5
+
+taken from https://github.com/r1chardj0n3s/parse/pull/34
+
+Python versions before 3.5 had a limit of 100 groups in regular
+expressions. This limit was removed during 3.5 development:
+
+http://bugs.python.org/issue22437
+https://hg.python.org/cpython/rev/0b85ea4bd1af
+
+The test_too_many_fields test asserts that the limit exists by
+attempting to parse a string with 15 fields, which triggers the 100
+named groups limit.
+
+Adjust the test so that if first checks to see whether the limit of 100
+named groups exists, and only assert that parsing 15 fields fails if
+that is the case.
