  "textContent": "Ddystopia:\n\n> Hello, what do you think about potentially adding a language feature that will allow forcing synchronous drop at the `await` boundary, with an error if value is used afterwards\n\ncan you expand on what that would look like ?\n\nDdystopia:\n\n> There exists lots of data structures that rely on the fact that they are not being held across `await` point, and that might help with it.\n\ncan you name some ? currently there is no way to ensure one is not held across an await point afaik.\n\ni guess a way that could work is a recursive auto trait that is mutually exclusive with `Future` ? that's a bit strange. should it cover `Coroutine`s as well ?",
