Patrik,

Please clarify.  I don't know what you mean by the 'with' and 'without' 
references.

And as long as I'm asking for more explanation, given the number of 
years of use the construct has had and for the number of different 
applications, where has the problem (whatever you mean specifically) 
been seen?
