If we keep this declaration here we need documentation about what it does and
how to use it.

It may be better to make this a private member (just because there is no need so
far for consumers to call this directly). In that case, the doc can be more
sparse.

I originally had it public just because there are lots of similar public
methods. I've moved it to private.
