The scope of imported identifiers in Modula-2
Terry L. Anderson · ACM SIGPLAN Notices · 1986
An extension to Modula-2 is proposed that allows better control of the scope of the unqualified form of imported identifiers. In the current language an imported identifier can be unqualified only for an entire module. Ada allows a more precise control of the scope. A fairly minor syntactic change to Modula-2 would allow a similar convenience.
