Simplify getters by assuming parameter expansion must be used everywhere
Simplify getters by assuming parameter expansion must be used everywhere

Since parameter expansion applies in all cases, there is no apparent
benefit to having the array getters return printed versions of the
arrays, since using the results typically means using the parameter
expansion syntax, anyway. Therefore, removing that functionality from
the getters greatly simplifies them and the functions trying to use the
results as arrays.
