I'm no linguist, so I might be just flapping my virtual gums, but it seems to me that when a given spelling means two or more different things in natural language, it's for historical reasons. For example, I'm sure that "dessert" was not designed to mean all of "a dry place", "a small meal after the main meal", and "to leave". It just kind of happened that way. I'd have to imagine that one of the finer points in learning a new language is distinguishing between words that are spelled the same. So, when it is said that it was intentional overloading of one spelling to mean multiple things, I have to scratch my head.
Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
