Re^2: ArrayRef of HashRef

    While zwon's ArrayRef[HashRef] does indeed match the question, it doesn't match the sample data, which isn't an ArrayRef of HashRefs. It looks more like an array of array-refs of hash-refs.

    The question needs to be clarified. Which question do you really mean?

    Update: fixed typo
