module vs class

[Raymond Lewallen]

Whats the difference in using a module with all public functions versus
using a class with all shared functions and a private constructor?

Raymond,

Whats the difference in using a module with all public functions versus
using a class with all shared functions and a private constructor?

In practice it's hardly any difference.

With a private constructor the class can still be instantiated from
within the class itself. A module can never be instantiated since it
doesn't have any instance constructor, not even a private one.
