I should have noticed this too; so in fact the current design can 
be used ignoring the scope modeling the C++ namespace. If the 
details of using such an external name in that fashion are 
identical to any other name at module scope in every context, 
then I therefore concede that the design is OK, because it may be 
treated as the alternative suggested in various ways in this 
thread by simply ignoring the new scope by not using its name.
