Yes, of course. It wouldn't make much sense to be able to save 'Access of a 
short-term local copy of the actual parameter -- you want the 'Access to 
directly access the actual object. (Recall the the original reason for 
"aliased" is to allow 'Access of the object. The rules for aliased 
parameters are a bit more complex, but the underlying issues are the same.)

Anyway, RM 6.2(10/4) specifically says: "A parameter of a by-reference type 
is passed by reference, as is an explicitly aliased parameter of any type."
