I kinda like the unicode idea because of the current dearth of usable
symbols. In fact, my system is already using utf-8.
$[charris@f9 ~]$ locale
And keymaps are not that hard to do in most editors. However... there are
various unicode encodings and locales, often indicated by the first few
bytes in a file. It's not clear to me that these encodings are universally
implemented at this time and I would be loath to depend on them without some
testing. Even so, it might be good to reserve a few symbols for future use
as operators. The resistance to adding these operators might be less among
Python developers because they are less visible, not multicharater, and
won't conflict with current python usage. So at the least I think we should
try to get some unicode symbols set aside and maybe several years from now
we can start using them.
Here is an interesting little article on unicode for
