Oh dear, no...

That's a might big assumption that 'all OOP languages' use references to 
pass objects - that's how it's implemented but there is (usually) no 
need in Ada for the programmer to get their hands dirty with such low 
level details!

Tagged types are guaranteed to be passed by reference (the cost of the 
tag alone makes this the obvious mechanism) and for other types the RM 
either dictates how it is done or lets the compiler select what's best. :-)

Cheers
