in thread Expanding / flattening a structure

Maybe:
# example structure
my $struct = {
    fruit  => [qw( apple pear )],
    type    => [qw( farmed organic )],
    period  => {
      20050824 => [
        to  => ['new york', 'london' ],
        ],
      20050825 => [
        to  => ['auckland' ],
      ],

    },
  };

Would be syntactically valid?

But given the only attribute to the date is to, why not remove that layer?

    two reasons for the 'to':

    1) the token 'to' names the values in the result,

    e.g. I end up with this in the expanded array of hashes: 

      to => 'auckland',

    2) also, this is just an example, in reality there are more values, e.g. 

      period => {
    20050824 => {
      to        => [ 'auckland', 'new york', ],
      transport => [ 'air', ]
    },
  },
