+This tests that a `Requires-Python` specifier that includes a Python
+patch version will not result in excluded a dependency specification
+with a `python_version == '3.10'` marker.
+
+This is a regression test for the universal resolver where it would
+convert a `Requires-Python: >=3.10.1` specifier into a `python_version
+>= '3.10.1'` marker expression, which would be considered disjoint
+with `python_version == '3.10'`. Thus, the dependency `a` below was
+erroneously excluded. It should be included.
