+// Legend:
+// `N` - number of combination, from 0 to 4*4*4=64
+// `Outer < Invoc` means that expansion that produced macro definition `Outer`
+// is a strict ancestor of expansion that produced macro definition `Inner`.
+// `>`, `=` and `Unordered` mean "strict descendant", "same" and
+// "not in ordering relation" for parent expansions.
+// `+` - possible configuration
+// `-` - configuration impossible due to properties of partial ordering
+// `-?` - configuration impossible due to block/scope syntax
+// `+?` - configuration possible only with legacy scoping
