It's an interesting feature, and nice if you want that sort of thing, but not something I'd personally want to see as the default. Deviating from the standard ASCII set of characters is just too much of a hurdle to usability of the language. If you really like that sort of thing though you might want to look into APL which is either famous or infamous depending on your outlook for needing its own custom keyboard in order to write it.
