Well nuts.  I use what seems to work and if there's a better way that I 
don't know about, then I don't know about it until I know about it.  I 
thought I learned that whenever 'nogob' was in effect that 'eval' was 
the only way to crack open a glob!  I've always hated it, so the above 
seems a huge improvement unless there's any gotchas with it.  So hard to 
really understand these myriads of syntactic tricks.   I'm still most of 
the time trying things by trial and error and saved snips of things that 
seemed to work elsewhere.  Real mastery is still some time off.  What 
would be useful is a sort of 'walk through' of some constructions so 
that the parse becomes human understandable.  Above I'd read: the local 
variable '_args' will be created as an array (split on God know what) 
set equal to the contents of the argument string (modified by the tilde 
in some way that I've never seen), the argument string being enclosed in 
'${}' because it is being modified ... so I almost read that one.
