We're spending a ton of time deallocating mostly empty maps, by reducing the number of maps we reduce the amount of memory used, and reduce map lookups.

It looks like this pull request may not have tests. Please make sure to add tests before merging. If you need an exemption to this rule, contact Hixie on the #hackers channel in Chat (don't just cc him here, he won't see it! He's on Discord!).

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

You know, thinking about this I think it might be preferable to go down the assoc vector route instead or in addition of this route. Let's chat you me and Dan.

If you want to refactor that later, thats fine, but we still need to reduce the number of containers.
