can you summarize the operators and the issues? The redesign for PVs 
were to allow indexes and names, then dynamic indexes and names, there 
was no redesign of the functionality, just that the functions behind 
were moved from xlog to core and renamed.

The NULL behaves differently for specific classes of PV, some delete and 
some reset. I do not recall right now if it is an item opened on the 
tracker, but if not, let;s open one and gather all these there.

AVPs and VARs do not have null values, also $r[uUd] - null gets a 
different meaning, like delete or reset. I don't see how to make it 
behave same for all PV, unless we remove the null, and stick to 
functions like delete or reset.

Cheers,
Daniel
