Desired output

(Don't mention E0277)
Rationale and extra context
When you read up on this error it goes on about whether I'm not implementing a trait. Nothing there talks about Sized, or why we're not implmenting it.
The current output error is very good, but that part is a bit misleading.

Research direction
Start by compiling the provided Unsized Rust snippet and inspect the compiler diagnostic path for E0277, since no source file or test is named in the issue. Done means the current diagnostic remains useful while the misleading E0277 code is omitted for this Sized-related error, with coverage for the reported case.
