/// ## Why is this bad?

/// This fix is usually safe, but if the lambda is called with keyword arguments, e.g.,
/// `add = lambda x, y: x + y; add(x=1, y=2)`, replacing the lambda with an operator function, e.g.,
/// `operator.add`, will cause the call to raise a `TypeError`, as operator functions do not allow
