This looks good as a first cut.

I think we should get a spec started for this.
We want to be able to get numbers that we can use for any language.
And have a way to track long term regressions.

But good start :)

Yup, this PR marks a complete set of basic aes testing for all languages. Next step is to create a superscript and aggregate the results in a comparable format, create a spec, more tests, ci, etc.
