Pass handlers object (self) to createHandler function

[chrisui]

This allows creation and reference of handlers in a single withHandlers call rather than many.

withHandlers({
  a: (props, handlers) => (...args) => handlers.b(...args),
  b: () => (...args) => doStuff(...arg),
})

Posting this here as a spitball idea. Will wrap up with tests if we think this is a fair addition to recompose!

This avoids the following requirement.

withHandlers({
  b: () => (...args) => doStuff(...arg),
})
withHandlers({
  a: (props) => (...args) => props.b(...args),
})

Note: this has definitely popped up as a somewhat edge usage 🤔

Idea super!
But have you tested your code as it seems like examples you provide will not work.
As handlers you use at createHandler are not the transformed handlers,
so to call b you need to call it like

withHandlers({
  a: (props, handlers) => (...args) => handlers.b(props, handlers)(...args),
  b: () => (...args) => doStuff(...arg),
})

and this is not cool.

Totally not tested the code! Just did a quick psuedo diff to demo the idea :)

As I said idea super!!! ;-)
