For your given example, both will require two hashes, each with 2 of the 8 slots used. As near as make no difference, the memory usage will de identical for both.

However, lets say you have 10 instances of a class that has 2 attributes:

  1. Classical: 10 hashes with 2 of 8 slots used ~ 80 hash slots + 20 scalars + 10 hash headers.
  2. Inside out: 2 hashes each with 10 of 16 slots used ~ 32 hash slots + 20 scalars + 2 hash headers.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
