+Subject: [PATCH] Make unit tests work with Ruby 3.4
+
+In Ruby versions up to 3.3, a label included just the method name.
+Since Ruby version 3.4, if a method has an owner, e.g. a class, the
+label is of the form `Owner#method`.
+
+To add Ruby 3.4 compatibility, soften up the predicate so it accepts
+either form.
+
+Fixes #41.
