Hi,

Thanks for the reply.  Yes, in the toy example I posted that would indeed
be an alternative.  Still, I'm wondering about the most general case;
suppose I had a function that took an object satisfying both foo_t and bar_t:

val do_something: < foo_t; bar_t; .. > -> bool

This is what I'm wondering if it's possible to express.

Best regards,
