# arr1 = [1, 2, 3, 4, 5]
# arr2 = ["foo", "bar", "baz", "abc", "def"]

try #zip

eg,


> arr1.zip(arr2).flatten
=> [1, "foo", 2, "bar", 3, "baz", 4, "abc", 5, "def"]

> Array.new(arr2.size+1,"|").zip(arr2).flatten[0..-2]
=> ["|", "foo", "|", "bar", "|", "baz", "|", "abc", "|", "def", "|"]

> arr2.zip(Array.new(arr2.size-1,"|")).flatten[0..-2]
=> ["foo", "|", "bar", "|", "baz", "|", "abc", "|", "def"]
