// 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
