The manual says:
In order to use variable variables with arrays, you have to resolve an
ambiguity problem. That is, if you write $$a[1] then the parser needs to
know if you meant to use $a[1] as a variable, or if you wanted $$a as the
variable and then the [1] index from that variable. The syntax for resolving
this ambiguity is: ${$a[1]} for the first case and ${$a}[1] for the second.
Does this help you?
