Many fields develop their own specific short-hand notation and vocabulary for communicating the complex yet recurring ideas within that field easily. In many cases, this is a modification of an existing language or, in some cases, many different languages.
This idea is a bit half-baked, but what if we could define a meta language that allows people to describe how to alter Python into some domain-specific language. Code written in the meta-language would be called a "domain specification" and it would describe new reserved-words and syntax for that DSL. It might even release some reserved words from reservation. This might provide an interesting way to try new syntax proposals. I don't know how something written in a DSL would interoperate with regular Python, they may have to use separate interpreters and pass messages between the two. I also don't know how you would link a script to a domain specification. Maybe this idea is less than half-baked. 1/4th baked? That way someone could write a version of Python where the assignment operator is "→" or "->" or "(╯°□°)╯︵ ┻━┻".
