+// a more thorough test for trait function/method calls from within trait function/method calls
+
+// This tests all combinations of caller+callee pairs. For each of these, the following combination of properties are tried:
+//   *) method (has self parameter) vs function (no self parameter)
+//   *) default vs overriden vs overriden (no default)
+
+// TODO: function calls via `Self::` are not yet implemented
+// Once this is implemented, this test should be updated.
+
+// test order is:
+// 1) trait method -> trait method
+// 1a) trait default method -> trait default method
+// 1b) trait default method -> trait overriden method
+// 1c) trait default method -> trait overriden (no default) method
+// 1d) trait overriden method -> trait default method
+// 1e) trait overriden method -> trait overriden method
+// 1f) trait overriden method -> trait overriden (no default) method
+// 1g) trait overriden (no default) method -> trait default method
+// 1h) trait overriden (no default) method -> trait overriden method
+// 1i) trait overriden (no default) method -> trait overriden (no default) method
+// 2) trait method -> trait function
+// 2a) - subcases are the same as the above
+// ...
