There was a proposal to use the "pillow" character for this purpose that wasn't adopted. This was good, because the pillow became the Euro symbol. Personally, if we're going to have such an operator, I like the idea of "\". This already has the interpretation that what follows should be interpreted differently in many UNIX programs and in C, and it's on most people's keyboards. It might also trick C people into thinking Ada looks familiar. -- Jeff Carter "When danger reared its ugly head, he bravely turned his tail and fled." Monty Python and the Holy Grail 60
