/**
 * An Event Operator that emits the value of the underlying <input> element into a target observer
 *
 * @category Event Adapter Operators
 * @returns OperatorFunction<Event, string | number | date | null>
 *
 * For simple, one-step input pipelines, see the {@link Cut | Cut (uppercase)} Event Adapter
 *
 * ## Examples
 *
 * ### ValidInfo
 *
 * Create a custom Event Operator that feeds a stream with validated data, once a custom validator passes
 *
 * ```ts
 * import { Subject, filter } from 'rxjs';
 * import { rml, inputPipe, value } from 'rimmel';
 *
 * const isValid = filter((s: string) => IS_VALID_IMPL(s) );
 * const ValidInfo = inputPipe(value, isValid);
 *
 * const Component = () => {
 *   const stream = new Subject<string>();
 *
 *   return rml`
 *     <input type="text" onchange="${ValidInfo(stream)}" autofocus>
 *     [ <span>${stream}</span> ]
 *   `;
 * };
 * ```
