*Easter eggs* (sort of) in Oberon.

There is one operator/symbol that Niklaus Wirth seems to be particularly fond of, because in Oberon it fulfils no less than 9 different uses. 

Question 1. Do you know which operator/symbol is meant?

Question 2. Can you name at least 8 different uses for this symbol? 

Extra credits if you can find the 9th use, which is a bit extraneous, but can be found in the book Project Oberon.
