| error[E0119]: conflicting implementations of trait `MyTrait` for type `MyFoo`: |
| --> $DIR/never-from-impl-is-reserved.rs:8:1 |
| | |
| LL | impl MyTrait for MyFoo {} |
| | ---------------------- first implementation here |
| LL | // This will conflict with the first impl if we impl `for<T> T: From<!>`. |
| LL | impl<T> MyTrait for T where T: From<!> {} |
| | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ conflicting implementation for `MyFoo` |
| | |
| = note: permitting this impl would forbid us from adding `impl<T> From<!> for T` later; see rust-lang/rust#64715 for details |

| error: aborting due to previous error |
