Nope.  You can have a function that returns a limited type.  The problem 
is that you can't assign the result.  But you can use the function in a 
name to get to a component of the object returned.

Very much a language lawyer point.  We are trying to extend Ada for the 
next revision to make constructors easier to write for limited types.

100% Ada, no bugs--the only way to create software.
