Hurl, a terrible (but cute) idea for a language

Re: Hurl, a terrible (but cute) idea for a language
#22Does it really need the toss/return syntax to loop? You could use
let loop = func(state, self) {
let next = foo(state);
self(foo);
};
loop(start, loop);Re: Hurl, a terrible (but cute) idea for a language
#23While cute this is really close to call/cc and/or algebraic effects as an abstraction for control flow, which isn't as much "cute" as it is "a powerful way to express programs in as few expressions as possible"

#24Fun experiment, but feels like a miss not to then explore the Optional type ideas and eliminate ‘catch’ all together.
Re: Hurl, a terrible (but cute) idea for a language
#25"Hurl" is terribly cute, but I suspect you could be even more successful if you had called it "yeet" :)
Rust already uses that for a similar feature.

#26A few years back I wrote a language called “exceptional” based on some shared ideas. Hurl is super neat and you took things further than I did.

Yep! Everyone should read https://overreacted.io/algebraic-effects-for-the-rest-of-us/ for how powerful this can be in practice. The caller gets to pause execution on the raising/hurling of an event - which makes many crazy things possible.

#29This is very fun!
I am only making suggestion because it rhymes with "hurl" (and it works well metaphorically for the repeating tossing/hurling): you could introduce a "whirl" keyword or part of the standard library as the way to handle loops.
It could be functionally the same as your loop example but removes the self-referential first argument (i.e. whirl(count, [1,3])).

#30If you squint a little, what OP has invented here is pattern matching with algebraic data types.
