From the component creation point of view, the approach taken by most
industrial-strength components is to provide a function so the client
can avoid doing something meaningless, such as trying to look at the
item referenced by an invalid position, but to also define and raise an
exception if the client ignores or doesn't use the function.

From the client point of view, it's probably best to use the function.
