In some recent news articles I noticed the following type of constructs:

	DEFINITION MODULE abc;
	FROM IO IMPORT Open, Close, File, Read, Write;
	...

	IMPLEMENTATION MODULE abc;
	FROM IO IMPORT Open, Close, File, Read, Write;
	...

It is not necessary to repeat the imports in the implementation module
since the all declarations of the definition module are automatically
known to the implementation module.  The implementation module only
needs to import names which are to be hidden from the definition module.
