/**
* Converts the arguments to an observable sequence.
*
* <span class="informal">Each argument becomes a `next` notification.</span>
*
* 
*
* Unlike {@link from}, it does not do any flattening and emits each argument in whole
* as a separate `next` notification.
*
* ## Examples
*
* Emit the values `10, 20, 30`
*
* ```javascript
* of(10, 20, 30)
* .subscribe(
* next => console.log('next:', next),
* err => console.log('error:', err),
* () => console.log('the end'),
* );
* // result:
* // 'next: 10'
* // 'next: 20'
* // 'next: 30'
*
* ```
*
* Emit the array `[1,2,3]`
*
* ```javascript
* of([1,2,3])
* .subscribe(
* next => console.log('next:', next),
* err => console.log('error:', err),
* () => console.log('the end'),
* );
* // result:
* // 'next: [1,2,3]'
* ```
*
* @see {@link from}
* @see {@link range}
*
* @param {...T} values A comma separated list of arguments you want to be emitted
* @return {Observable} An Observable that emits the arguments
* described above and then completes.
* @method of
* @owner Observable
