There is some validity to this reasoning though: adding a new keyword
risks conflicting with variable names in existing code. If we add a
new keyword "foo", all the code that has a variable named foo is going
to break, but if we add a new operator "++", we don't have to worry
about some code having a variable named ++, as it's not a legal name.

(Not arguing we should add the ++ operator... just an example! :) )
