React utils
// Jan 2023
/**
* Provides better intellisense for JSX Components at call-site by allowing them to accept additional generics.
*
* In some cases it also switches `onChange` handler from `(value: string) => void` to `(event: HTMLInputEvent<..>) => void`
* to be used with `useFormState()` hook's e.g. `onInputChange` which accepts `EventStub` (`(ev: { target: { name, value }}) => void`).
*
* @example
* interface FormState {a, b}

Typed compose
/**
* @name compose
* @summary Composes Higher-Order-Functions from right to left so that they are executed from left to right.
* note: To compose Higher-Order-Components, use compose.ts
*
*
* @description
* Two overloads are available:
* A) Matches the composed signature of whole compose to the wrapped function.
* B) As an escape hatch, it is possible to explicitly define the resulting OuterSignature with a generic, ignoring the HOFs types.
