You could also wrap this in a native interface:
my $obj = new BrowserUKStruct; tie my %hash, "BrowserUKHash", $obj; tie my @array, "BrowserUKArray", $obj;
It should be quite easy, with all the tie methods simply translating.

You'd have to decide on a proper interface though, like is what you set also what you get (is $hash{key} an array reference of index and value?). You could also decide, for simplicities sake that the hash and array interfaces are read only, and modify the object directly.

I think this is a wonderful example of where perl fscking kicks a**. The ability to glue an arbitrary store, like an object, into a hash and array interface, simultaneously is simply superb. Moreover, this is a good example of what tie comes to solve. By giving you the possibility of treating your hash-like and array-like data as real hashes and arrays, you learn a good lesson about the value of abstraction, and polymorphism. Well, I did, at least, when I was obsessed with tie.
