Describe the bug
black --preview crashes on seeing await (yield)
This is certainly not good code or anything, but is code we have in one of our test files in flake8-trio. Non-preview black has no issues with it.
To Reproduce
For example, take this code:
async def foo():
await (yield)And run it with these arguments:
$ black --preview myfile.py The resulting error is:
error: cannot format myfile.py: blib2to3.pytree.Node object expected; got blib2to3.pytree.Leaf
Oh no! 💥 💔 💥
1 file failed to reformat.
Expected behavior
Not crashing
