-   * Reports an error and then aborts the compiler. Avoid using this method.
-   *
-   * In order to support incremental compilation, it is preferable to use
-   * [reportError]. However, care must be taken to leave the compiler in a
-   * consistent state, for example, by creating synthetic erroneous objects.
-   *
-   * If there's absolutely no way to leave the compiler in a consistent state,
-   * calling this method is preferred as it will set [compilerWasCancelled] to
-   * true which alerts the incremental compiler to discard all state and start
-   * a new compiler. Throwing an exception is also better, as this will set
-   * [hasCrashed] which the incremental compiler also listens too (but don't
-   * throw exceptions, it creates a really bad user experience).
-   *
-   * In any case, calling this method is a last resort, as it essentially
-   * breaks the user experience of the incremental compiler. The purpose of the
-   * incremental compiler is to improve developer productivity. Developers
-   * frequently make mistakes, so syntax errors and spelling errors are
-   * considered normal to the incremental compiler.
