This test detects use of the functions Equal?, Not Equal?, Greater?, Less?, Greater Or Equal?, and Less Or Equal?. If either of the inputs to these functions is a variant or contains a variant, the test returns a failure.
In some cases, comparing variants can result in a temporary data copy, which can cause performance issues with large variants. If you are comparing against an empty variant, consider using the Empty String/Path? function, which can also check for empty variants, and does not create the temporary data copy.
