# Let's say I have this the following array of strings that are usually dynamically created:
array = ["one", "two", "three", "four", "five"]

# I would like to to use this array to create the following hash, using the items from the array as the keys and then also using them to set the value by referencing another hash, as follows:
hsh = {"one" => some_other_hash[:one], "two" => some_other_hash[:two], "three" => some_other_hash[:three], "four" => some_other_hash[:four], "five" => some_other_hash[:five]}
