Do you mean, in VHDL you can write "use P;" without "with P"? (Or what 
kind of Syntax VHDL uses for Ada's "with Name" and "use Name" ...)

Or do you mean you can write "P.Some_Procedure(...)" or "P.Some_Type" 
without any "with" or "use" before? The compiler can certainly search for 
package P in such a case just as if you wrote "with P" at the beginning of 
your compilation usage, the explicit "with P" is for the human reader.
