Getopt::Long has two usages - either by passing in variable references or a hashref within which to have GetOptions() set keys and values. Using the first method allows for multiple entries for the same key (using an arrayref). However, reading the perldoc for Getopt::Long doesn't tell me how to allow for multiple entries of the same key using the hashref method.

As I'm working with some 10-12 options, I need to use the hashref method. (Don't ask - not my design.)

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
