Move several examples from the docs to tests and then `literalinclude` them

2

We have several quite large examples that live in our docs: 1. https://github.com/dry-python/returns/blob/master/docs/pages/future.rst#futureresult 2. `Number` example from: https://github.com/dry-python/returns/blob/master/docs/pages/contrib/hypothesis_plugins.rst#check_all_laws 3. https://github.com/dry-python/returns/blob/master/docs/pages/context.rst#requirescontextfutureresult-container What needs to be done? - We need to extract...

Consider adding decorators to work with generators

2

After think a lot about #355 it will be great to provide the same mechanisms we have to "normal" functions to generators! It is not uncommon to see generators in...

Consider adding `to_iterable` converter

6

After #244 we now have `.from_iterable` constructor on every container. We should also add `to_iterable(container: Container[Sequence[T]]) -> Iterable[Container[T]]:` (where `Container` is just an alias, we should support types for all...

Consider adding `Lazy` protocol

1

We can add `Lazy = () => A` protocol to `returns.primitives.types` This might be helpful when working with `IO` when someone want to slow things down. One should use `Protocol`...

Try to provide default implementation for some interfaces

2

For example, `.map` is just `return self.__class__(function(self._inner_value))` in many cases. There are also other methods that can be possibly have defaults. Or `.from_iterable` also is the same for every container....

It is similar to `Result`, but also has the third case: when we have both `Success` and `Failure`. Link: https://github.com/gcanti/fp-ts/blob/master/src/These.ts

Add `Identity` monad

4

We need this to wrap regular values into a monad. This might be required when you have a function like this: ```python @kinded def do_something(c: KindN[V, E, D], f: Callable[[V],...

Improve docs: why do we ignore almost all the FP jargon in this project

Consider adding `Observable`

This can be released as an independent library: https://github.com/ReactiveX/RxPY

Unit method like `IOResultE.from_value` must return `IOResult[_V, Exception]` type

9

Currently, they do return incorrect types: ```python reveal_type(IOResultE.from_value(int)) # => IOResult[int, Any] # Should be: # => IOResult[int, Exception] ``` To achieve what we want we might tweak the way...
