I don’t agree that there is no realistic hope of that changing.  It appears to be pretty reasonable to anticipate that we’ll all be using software-driven keyboards that can display software-defined symbols on the keys in the relatively near future (probably 5 years, certainly 10).  All kinds of interesting things become possible when that happens, including the ability to make unicode operators much easier to discover and type in a programmer’s editor.
