Hi, I am trying to parse some command line options of the form (using Getopt::Long): 
-cmdline_option REG1=value1, value2, value3, value4
-cmdline_option REG2=value1, value2, value3, value4
...
-cmdline_option REG500=value1, value2, value3, value4
...

[download]
and so on.
In the same program, I can parse another command line option of the form: 
-cmdline_option_done REG1=Value
-cmdline_option_done REG2=Value
-cmdline_option_done REG3=Value
....

[download]
using the following format specifier in @opt_array 
-cmdline_option_done=s%

For my present requirement, I need to be able to get a format specifier to accept not just a hash with key, value pairs as strings, but a hash format specifier where the key is a string, but the value is an array / array reference. Something like this: 
my %opt = (
    
     'reg_ll_ul_pc_zp' => {
 
         REG1 => [0, 100, 100, 0],
         REG2 => [0, 100, 100, 0],
         REG3 => [0, 100, 100, 0],
         REG4 => [0, 100, 100, 0],
         REG5 => [0, 100, 100, 0],
         REG6 => [0, 100, 100, 0],
 
     },

    );

my @opt_array = qw(

    reg_ll_ul_pc_zp=s???? ( :( )

   );

GetOptions(\%opt, @opt_array);

Any help with tackling this issue would be greatly appreciated! Thanks in advance.
