I should have said:

	Also, USE-PACKAGE must be modified.  The current USE-
	PACKAGE signals an error if there is a symbol that
		1. is present in the USEing package,
		2. has the same name as an external symbol
		   in the USEd package, and
		3. is not in the shadowing symbols list of the 
		   USEing package.

My patch code for the C function use_package in file
c/symbol.d works as you are expecting.
