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.
