intresting, in the past I used to think that having a couple more of
nice simbols on the keybords, like those, expecially for parenthesis
would have been a good thing to foster the immagination of language
designers.
Now, i realize that having a little set of simbols reduces the number
of concepts we can have in the language with an elegant syntax, and
that pushes us to design languages with less concepts, that is sort of
good....
