- I don't think that would be such a good idea.

- Speaking as a fluent user of C, I don't think the general public
- is ready for '++' and '--'. I think it should be intuitively
- obvious (that was my math teacher's phrase for "Duh.") that non-users
- who see '++' will logically expect it to increment by *2*. (2 '+' signs,
- 2 increments. Obviously.)
