Hi Sergey This is great! Can you explain what "supports unpacking" means against the entries for =: and =. ?

I thought somebody might find it useful too. Here's the link: https://sergeyqz.github.io/jcheatsheet/. The main idea was to have a one-page plain HTML table of all primitives with short descriptions, synonyms (e.g. Member (In) has "contains, includes"), and argument types. It's far from perfect, I'm sure there are mistakes. For example, I didn't pay much attention to types yet, some descriptions are not clear enough, but I find it helpful as it is. I posted it on r/apljk last month and got thoughtful comments from u/moon-chilled. Maybe somebody here have more to say, I'd appreciate any feedback.
