Public API for @_memo?

[sirscriptalot]

Hi all,

I was curious what you all thought about making an accessor for @_memo? I personally use it to memoize expensive methods and finders like what is done internally with references. It isn't too important, I just feel a little uncomfortable depending on a private variable like I am and also don't like patching reload_attributes to add a new hash that does the same thing as memo.

Thinking through some of the negatives, I noticed ohm-crystal doesn't memoize associations and maybe that is something you'd want to remove from ohm (ruby) as well? Also, I suppose users could clobber the existing memo keys unintentionally. I don't think it's worth it to update the reference helper to namespace associations on the memo hash, that seems like a user error if someone is using the same keys.
