The thing is, they're not really any different to keywords in how 
difficult they make the language to learn, in how much complexity they 
add to the compiler, and in how much complexity they add to the spec.
We could even add an @ to the start of every existing keyword, and then 
argue that the language has no keywords at all! So we still need to be 
reluctant to add any new ones.
