Looks like [ChainRec](https://github.com/gcanti/fp-ts/blob/82e05311a1d0df71829fff75c4cb4f77032d6368/src/ChainRec.ts)

@christianbradley I fail to understand what's the problem with ```ts import { option as O } from 'fp-ts' import { pipe } from 'fp-ts/lib/pipeable' const toUpperCase = (s: string): string...

side by side ```ts import * as E from 'fp-ts/Either' import { pipe } from 'fp-ts/function' declare const getNamePrefix: () => E.Either declare const getFirstName: () => E.Either declare const...

Note that `getMonoidSame` doesn't return a `Monoid` ```ts const M = getMonoidSame() console.log(M.concat(1, M.empty)) // => undefined, should be 1 ```

@paulvitic you can find some help (and links) in the documentation, so for example: - `monoid.fold`: "Use `concatAll` instead" (https://gcanti.github.io/fp-ts/modules/Monoid.ts.html#fold) - `io.getMonoid`: "Use `getApplicativeMonoid` instead" (https://gcanti.github.io/fp-ts/modules/IO.ts.html#getmonoid) etc... p.s. If you...

In general curried (or data-last) functions are supposed to be used along with `pipe`: ```ts import * as Eq from 'fp-ts/Eq' import { pipe } from 'fp-ts/function' import * as...

fair enough, what do you suggest?
