`USE` `ONLY` Statement

Another way to avoid name clashes is to only use those objects which are necessary. It has the following form:

 
USE < module-name > [ ONLY:< only-list >...]

The < only-list > can also contain renames (=>).

For example,

    USE Stack, ONLY:pos, &
           IntegerPop => Pop

Only pos and Pop are made accessible. Pop is renamed to IntegerPop.

The ONLY statement gives the compiler the option of including only those entities specifically named.
