I agree it's a bit annoying, but a better solution than using `as` is just telling reduce what its generic type should be:

tasks.reduce boolean>>((acc, item) => ..., {})

Also imo it's cleaner to reduce to an object with something like this as the callback:

(acc, item) => ({ ...acc, [item.label]: t => t.label === item.label })

oh man I somehow never realized I could just use that square bracket syntax. must update everything
