Detailed Description

Annotates a diagnostic with some code that should be inserted, removed, or replaced to fix the problem.

This kind of hint should be used when we are certain that the introduction, removal, or modification of a particular (small!) amount of code will correct a compilation error. The compiler should also provide full recovery from such errors, such that suppressing the diagnostic output can still result in successful compilation.
