Well, I was interested in binary operators on integers
and as Peter suggested that I should look into it
myself, so I did it.
Choice of operators:
~ - not
& - and
# - xor - I like it :)
| - or
Things I am unsure of:
1) Precedence. I quite nonscientifically hacked in gram.y,
and could not still make it understand expression '5 # ~1'
nor the precedence between '&' and '|#'...
At the moment all the gram.y changes could be dropped and
it works ok, but without operator precedence. Any hints?
2) Choice of oids. I took 1890 - 1913. Should I have taken
directly from 1874 upwards, or somewhere else?
3) Choice of operators. As I understand the '^' is taken,
I wont get it. Now, in gram.y I found that the '|' is
used in weird situations and with weird precedence so
maybe I should use something else for OR too?
4) Is anybody else interested? ;)
I would like to get comments/further hints on this...
