It seems to me that tools that search for r"^\sdef\s+spam\s(" are They would likely search for something like r"^\s*def\s+[a-zA-Z0-9]+" which will hit "def async spam" but not "async def”.
Realistically that can’t be what they’re doing because of multiple string literals, internal-scope functions, etc. But I agree with Steven that guessing here is pointless. More importantly, consider:
- if we optimize for some unproven backwards compatibility with tools, we’re sacrificing better readability of “async def foo()”
- if that tool wants to work with Python 3.5, it’ll still have to support “await” so we’re going to be incompatible anyway; let alone “async for” and “async with”
So all in all, I don’t buy this argument.
