Maybe I'm lost about the greater theory here. As a non-js dev it looks like they're just adding some OO sugar to events. I hesitate to call it sugar because it seems a lot more verbose than "my-menu.show-popover()" but its better than a global listeners I suppose.

COMEFROM is one of the many great jokes that form the Intercal language. I recommend reading the language specification.

Of course, COMEFROM's grown up (and very real) sibling is ALTER GOTO in COBOL.

So I tracked down this programming manual for intercal https://3e8.org/pub/intercal.pdf and can't locate any mention to comefrom.

It is from a dialect called C-INTERCAL and is written with a space: 'COME FROM'

Thanks for that correction! I had memorized COME FROM as part of the original Intercal. My mistake.

It's also foundational in Threaded INTERCAL, where "multiple COME FROM statements with the same label cause the program to fork separate threads at each COME FROM":

That’s a reasonable analogy, but I think the more novel and interesting thing about this is that it’s:

- A declarative mechanism to relate one element to another

- With a range of semantics for declaring interactivity invoked through their relationship

- At a high level, with explicit guarantees of consistent accessibility and UX

In a lot of ways, this looks a lot like what people describe when they wish for more HTML and less JS. (Except for the extreme-minimalist version of that which rejects web interactivity altogether.)
