Class [1] (at the moment it works only with 1st one), check that works with
is / instanceOf, revisit the cast function accordingly and maybe other
things not yet in my mind and especially check FP won't complain using it.

Exciting to see these kind of experiments. A really good usecase for
private constructor would be to create a Singleton class, I.e a class that
cannot be instantiated outside of itself. Would that be something you can
test for?

Flash Builder that built an abstract syntax tree to support intelligent
editing. We used it as the beginning of Falcon's lexer and parser. The code
is just looking at the AST to see if the constructor has a non-public
namespace.
