I'd use it for the generic object construction utility I sent mail about 
a few days ago. The constructor parameters for facade<Object> should be 
the constructor parameters for Object, plus any additional parameters 
facade<> might need. So I need to be able to manipulate Object's 
parameters<> at compile time.
