I want to have an array of 'names'.
given a name, "X", I had a prefix, _p_, so have _p_X,
I want to access / manipulate it as an array.
so given I pass in a name in a var, I have to use 'indirect' syntax:
${!name}
But that doesn't seem to play well with array syntax:
${#${!name}[*]}
bash: ${#${!name}[*]}: bad substitution
What syntax would I use for this?
