As someone has already said, if 'new' itself throws an exception, then maybe
this isn't relevant. But I've wanted to check in programs whether or not a
var has been 'filled in' or not.

I half-recall the spec. saying that one mustn't 'use' vars before allocating
something to them, but anyway, the way with operator-> is simply:

assert(compound_var.operator->() != 0)

I don't think CORBA::is_nil() is any good - isn't that only for object
references?
