+// - BOOST_PP_REPEAT, BOOST_PP_REPEAT_2ND, ... must work
+// together.
+// - BOOST_PP_REPEAT is already tested with
+// BOOST_PP_ENUM_PARAMS.
+// - The tested repeat count should exceed imaginable usage.
+// - Testing the generation of is_function_helper()s upto 40 arguments should
+// be sufficient in this case. Many compilers may fail the repetition tests
+// (at least with higher counts). However, the primary purpose of the
+// repetition primitives is to enable configurability with reasonable
+// defaults, and not necessarily "the most impressive repetition".
+// - ENUM_SHIFTED_PARAMS must be tested so that the shifted range is shown to
+// be correct.
