Function bind

Chains eithers, where it returns out a Left if one of the composed functions returns left. Or return the Right value if all succeedes with the composed value from the last chain computation.

Example

const validate = (str: string) =>
  str === 'correct' ? right(1) : left(new Error('string has to be "correct"'))

chain(validate, right('correct'))
  .unrightOr(throws) // -> 1

chain(validate, left('error'))
  .unrightOr(throws) // -> throws error

```
