I refrained from including these details on the original post because they're subject to immiment obsoletion. These tools are changing and evolving quickly, and some of these instructions are likely to become outdated in the coming months or even weeks.

The main tool

When evaluating the available transpilers, I decided to use 6to5, which has recently been renamed to Babel. I chose it based on:

	could in theory allow asyncio round trips to a pure async DB driver like
	asyncpg.

	The approach here seems too simple to be true and I did not expect it to
