Could someone please show me a practical example of how one would use Data::OptList? MST mentioned Moose 'with' syntax and DBIx::Class 'add_columns' as examples, but I think those are too involved to get a basic understanding of this module.

One very confusing thing about this module is the description starts off saying

Hashes are great for storing named data, but if you want more than one entry for a name, you have to use a list of pairs
But then the docs show named data where is not more than one entry per name: 
$values = [
    foo => undef,
    bar => undef,
    baz => undef,
    xyz => { ... },
  ];

Assuming that 'entry' is synonomous with 'value' and 'name' is synonomous with 'key'.

In reply to Data::OptList - I just dont get it by metaperl
