Last reply. Probably. Here's `maybe` in TypeScript: const maybe = <T,>(f: (_: T) => T, d:T) => (x: T|null) => f(x || d); console.log(maybe((x) => 2 * x, 3)(null)); // returns: 6

Got `maybeOut` wrong, can't edit, but it should be: maybeOut :: (a -> b) -> (a -> Maybe b) maybeOut = (.) Just Also the parenthesis around the last two output types are added for emphasis, but can be safely removed.

I get it! (Thanks, playing around with actual code helped a ton.) For example, in Typescript you're saying you can add a default value simply: # old function f(x: number): number { return 2 * x; } # new f

Generators require a __next__ method, yield statement, or generator comprehension. What you've got is lambdas and a list comprehension. Rewriting using generators would look something like: items = [1,2,3,4] gen1 = (x*2 for x

It must . If it is possible to rewrite `X -> Y|Null` as `X|Null -> Y` without changes to external code, then the `X` type needs to accept `X|Null` and the `Y` type needs to accept `Y|Null`, therefore any `T` must implicitly be `T|Nul

I have no problem with the math, I take issue with your assumptions to get there, namely that these panels will be anywhere near cost-competitive with traditional panels. I hinted earlier that this new panel is manufactured by taking a trad

The... uh... manufacturer's press release? That's your basis for "it's literally free energy"?

Sure, but again... If that panel gives you 20% more energy for a different cost, than the extra 20% is not free energy. I'd have assumed a tandem perovskite on silicon panel probably costs more than a traditional silicon one. Do you di

Your understanding is not quite correct. It's 20% efficiency vs the traditional panels which max out at 20%, totaling 25%.
