I don't get it.  The docs say that scalar split returns the number of 
elements.  That's useful and convenient, and more intuitive than some of 
the alternative gyrations that have been suggested.  No one cares about it 
shoving the contents in @_ or wants that to continue, especially since it 
results in a warning.  So why can't we make it return the number of 
elements without either populating @_ or generating a warning?
