Thanks for the suggestion. The closest to a side by side is here (http://rzimmerman.github.io/kal/#asynchronous-wait), and also the table of operators in the readme (https://github.com/rzimmerman/kal/blob/master/README.md#oper...). Also the examples directory on the github repo.
Apologies if you saw these already. I'll add something like what you suggested, though.
