Return true if the specified lhs and rhs objects have the same value, and false otherwise. A nullable object and a value of some type have the same value if the nullable object is non‐null and its underlying value compares equal to the other value. Note that this function will fail to compile if LHS_TYPE and RHS_TYPE are not compatible.
