Hi,

I think the idea is that the type would be declared inside
a module that would provide constructor functions.  Moreover,
because private is not abstract, it would allow the outside
world to pattern-match on values of that type.  This is actually
a very useful feature.

Btw, the code works on 3.11 CVS!

Cheers,
Dario Teixeira
