It generally does not make sense: If you know all your local variables
you do not need a dynamic approach.  If you need dynamic variables you
better stuff things in a Hash because you cannot create local
variables dynamically which could be seen.  I am aware of only one use
case where it may actually make sense.

What are you trying to achieve?

Kind regards
