There is fundamental problem which such a construct even using normal 
Pascal scoping rules. The identifier "test" in this case, is in the 
symtable of procedure B, which is a deeper lexical level, thus can hide 
global identifiers.

On the other hand:

uses a;

var a:byte;

... both unit a as variable a would go into the global symtable, which 
is the same lexical level, thus causing duplicate identifier conflicts.
