What I meant was this seemed to be a candidate feature for the next 
standard, or F2013 as you coined it.  There shouldn't be much of 
implementation hurdle once all the language semantics are sorted out. 
After all, compilers have dealt with the data selectors.  It's more of an 
issue of standardizing the feature so everyone agrees with the semantics.

This appears too big a change to F03, plus the door to interps to F03 has 
closed, right?
