The following code is compiled in 3.7, but is a syntax error in 3.6.
async def f(x):
f"{await x}"
I have not found mentioning this change in What's New, and it looks grammatically correct. It looks as a bug in 3.6.
It may be too later to fix it in 3.6, but at least it should be documented.

The answer I got from Yury before was: "Before 3.7 async and await were not proper keywords, so the interpreter did not recognize them in some contexts." |

Yes, await was recognized only in asynchronous functions. f-strings involve a separate parsing step for subexpressions, and it is not aware that it is in an asynchronous function. Seems the fix was unintentional, but it should documented in any case. |

Hey, I'd like to work on this issue. Seems like an easy fix. Can you please help me out with where I will need to add the documentation for this? |

There was no update on this since 02/04, so I will work on this as I am at the PyCascades sprints right now. |

Thanks for the PR! We don't normally accept doc changes for branches in security-fix mode but this seems like a worthwhile exception. |
