Visibility of packages in child bodies...

Visibility of packages in child bodies...

[Dale Stanbrough]

If a series of library packages are created as...

	package useful is...
	
	package a is...
	
	package a.useful is...
	
then in the package body of a.useful is it possible to
refer to package "useful" without using a library level renaming?

e.g. in the following...

	with useful;
	
	package body a.useful is...
	
package "useful" is not directly visible.


The apparent solution...

	with useful;
	package useful_renaming_because_of_collision renames useful;
	
	
	with useful_renaming_because_of_collision;
	
	pacakge body a.useful is...
	
seems a bit annoying, in that a new library entry has to be created.

But, for sure, it is possible to refer to STANDARD.useful.
And you can use the "local" renamings of STANDARD.useful instead of
(annoying) library level renaming.

with Standard.Useful;

should do the trick. All library packages are children of Standard.
