Thanks! But what about
a {
 b {}
}

That's the same as 
a b {} right?

That seems counter to your example with c & a as the c is outside the scope but in my example b is inside the scope. Both don't use the &.

I'm saying only that not using the & is indeed shorter but leads to inconsistency, which makes the coffee harder to read, especially for novices
