An array is a list of scalars. Hashes are not scalars. Ergo, arrays cannot contain hashes.

There are two workarounds if you want to store a hash in an array:

  1. References are scalars. Therefore, you can store a reference to a hash in an array.

  2. Strings are scalars. If you can serialize the hash into a string, you can store that in an array.

There is no #3, and it is almost always a terrible idea to choose #2 over #1.

Why exactly are you trying to avoid using references?
