What does Module.private_constant do? Is there a way to list only private constants?
Starting in Ruby 1.9.3, we can create private constants:
module M
class C; end
private_constant :C
end
Is there a good documentation about what this does? Is there a way to get the names of only private constants similar to calling constants
