Is there a module that provides functionality like Template Toolkit does when accessing a deeply nested data structure? I want to pull out something like $a = $hash{first}[0]{second}{third}[3] without having to test each part of the structure to see if it conforms to what I expect. If %hash = {} I want $a = undef, not produce an error.
