there is no change to uno only how basic handles an already acquired uno 
structure ( either one defined locally or fetched from some other uno 
operation )

being bitten ( often ) by changing basic I understand the fear :-) But, 
I can't see that this change would be 'dangerous' it surely is the 
correct and desired behaviour ( but maybe indeed I am missing something 
and perhaps influenced by a long irritation with the way it worked 
before ). Of course the caveat is there is always a risk of some 
unexpected side-effect with any change ( especially true in basic )
