Typescript mapLeft not found #648

Closed codingedgar closed 5 years ago

codingedgar commented 5 years ago

Hi! Incredible library 👏 thank you 🙏

I'm using Sanctuary with Typescript (@types/sanctuary@0.14.2) and the type of S.mapLeft does not appear anywhere, so i'm unable to use the function.

Is there any way i could contribute to add this type or maybe there is a workarround or is included in another version?

Thank you in advance 🙏

@vicrac and I are updating Sanctuary's type definitions in DefinitelyTyped/DefinitelyTyped#37879. I have encountered several problems as a result of TypeScript's lack of higher-kinded types and its intentionally simplistic type resolution algorithm that replaces many type variables with any.

Let's move this discussion to the aforementioned pull request. :)
