[Petal] Petal::Hash - get vs. fetch

[William McKee]

Could someone who is familiar with Petal::Hash enlighten me as to the
difference between get and fetch? I am working on a modifier that will
take a key of an arrayref in the hash and return a random subset of
items from the list. I'm finding that both get and fetch are returning
the same list for me. Should I use one over the other?

Thanks,
William
