> This is an improvement of the {{addValue}} method.
> Previously, the method returns a boolean, indicating if the value has been
> successfully added to the dictionary.
> After the change, the method returns an integer, which is the position of the
> value in the dictionary.
> The purpose of this change:
> # the dictionary position contains more information, compared with a boolean
> indicating if the value is added successfully.
> # this information about the index in the dictionary can be useful, for
> example, to collect statistics about the dictionary.
> With the dictionary position, the information about if a value has been added
> can be easily determined.
