forEach<T>(action: (x: T, i: number) => void): (src: Iterable) => void
Executes the provided action for each element in the source iterable.

Curried version of _forEach.
Type Parameters
- T
  Element type produced by the source iterable.
Parameters
- action: (x: T, i: number) => void
  Callback invoked with the current value and index for its side effects.
Returns (src: Iterable) => void

Example
```
const log: Array<[number, number]> = [];
_forEach([10, 20], (value, index) => {
  log.push([value, index]);
});
console.log(log); // [[10, 0], [20, 1]]
```
or using the curried version:
```
const log: string[] = [];
pipeInto(
  ["a", "b"],
  forEach((value, index) => {
    log.push(`${index}:${value}`);
  })
);
console.log(log); // ["0:a", "1:b"]
