My system uses arrayrefs of arrayrefs containing what are in effect key-value pairs, e.g.:
$pairs = [
['fish','fry'],
['clam','bake'],
['wiener','roast'],
];
It uses this data structure rather than a hash because it works better with the algorithms used in some places. I would like to access the data, however, as if it were a hashref, with similar syntax.
Here is a construct I came up with:
my $party = {map{@$_}@$pairs}->{'fish'};
The value 'fry' will be assigned to $party.
The one caution is that if there is more than one element in $pairs with the key 'fish' (there should not be, but...), there may be problems. I believe the last element in the array with this key will be used.
Does anyone have thoughts on this? Is there a better way to do what I am describing?
