OK yeah bad analogy. My point is that if you say "only what 
syntactic sugar is necessary" it doesn't really help because what 
does "necessary" mean? If you take it literally you dont need for 
and while loops because you have if and goto. But pretty much 
every language has them, so obviously there's more too it.

its a great quote and you can see the wisdom in it but there's a 
lot lurking under the surface of the words "essential" and 
"necessary"
