I am confused, you can indeed add "markers" (via weak tables if you
prefer a not
invasive approach) allowing a syntax like:

example = M{
   a = A{1,2,3},
   b = M{a = 1, b = 2, c = A{1,2}},

Would this be fine?

This is what I meant by "In your own code you can choose a way to
flag a table as a List/Array or a Map". You can enforce a convention
like that in your library but it is not something standard. If you
already have a "standard" Lua structure composed of tables and
basic types you cannot determine what is Array-like without
iterating every single table in the structure.

Examples of this can be found (for instance) at [1] and [2].
