Implement for pieces of information that require some additional context Context in order to be checked.

§WARNING

DO NOT USE IN PRODUCTION. This is only meant to be used in testing environments. A runtime compiled with try-runtime should never be in production. Moreover, the name of this function is deliberately chosen to prevent developers from ever calling it in consensus code-paths.
