Hi again, having re-read your message, here's the next blob. :-)

Yup, but they're rather called "special characters". Symbols are those unique Strings that begin with a # character - and, as I wrote earlier, all selectors are, internally, represented as Symbols. What was the precise message that Squeak gave you when you tried to implement +? It might be that replacing an existing implementation of + with another is prohibited, depending on the class you want to do it in. (Number might well be an example of that.)
