There&#39;s nothing wrong with your ideas if you were designing a language from scratch. However, Python has a long history and many tools and uses for the same operators you are considering. And even has a current &quot;insert&quot; operator (slice assignment).<div><br></div><div>When adding a new feature, you need to consider if you&#39;re duplicating current functionality and if a 2nd &quot;obvious&quot; way is worth breaking the Zen.</div><div><br></div><div>Also, consider whether your &quot;intuitive&quot; design is following or breaking a de-facto standard established elsewhere in the language.</div><div><br></div><div>For example, if you&#39;re making a file format decoder, you should create functions &quot;load&quot; and &quot;dump&quot; to behave like every other file format decoder module.
