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.
