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