Unless somebody wants to do a survey of editors and IDEs and other tools, arguments about what regex they may or may not use to search for function definitions is an exercise in futility. They may use regexes anchored to the start of the line. They may not. They may deal with "def async" better than "async def", or the other way around. Either way, it's a pretty thin argument for breaking the invariant that the token following def is the name of the function.

Whatever new syntax is added, something is going to break.
