Like I said its a back door aproach, it circumvents the parser. which
doesn't allow this syntax
${${Name}[1]}
I didn't actually find this myself it was reproted on this list a long
time ago. I do remember Chet saying he wouldn't break it. But other
than that I can't remember the discussion all that well. As always with
this topic it was a pretty lively debate.
Yhea its a constant fight getting my email clients to stop
capitialising various things in code.

I'd shared this advice ("don't use it"), because I cannot for the
life of me tell whether this is a bug or a feature. As near as I
can tell, it is an unforeseen consequence of the parser implementation,
not documented anywhere. As such, I would not rely on it to continue
working in future Bash releases.
P.S. you meant printf -v, not -V.
