I don't understand this part. Any techinique for accessing the "stringified"
form of the variable name would require using that very string as input no?
What do you need to do other than the following?
my $filename = "somename.dat";
If the question is "How do I find the names of all the arrays in a
package?", then you probably shouldn't be using package variables for this.
Use a hash to hold those arrays instead.

This is the thing the FAQ says not to do. Just don't do it. Use a hash.
Consider: what if the filename is "INC"? Do you want to trash @INC?
