It has to be. Missing is e.g. the one I introduced*. Symbol is a upside 
down hat with two ears sticking out. Pronounced "Wabbit" and can be used 
at the end of an equation to signify that the reader is not supposed to 
understand why this equation is used until later.

The need for this symbol arises from the fact that mathematical 
derivations are often presented not the way the idea came up but in the 
reverse order. Mainly because that appears to be the style of 
mathematics: never admit that you had a brilliant idea to start with. 
This practice is meant to impress the readers, but mainly results in too 
many kids deciding that they will never understand mathematics.

*) I did that in the proceedings of a very small conference, so I don't 
blame anyone not to have read it.
