A function/method/property name can be merely *read*; a closure must be *interpreted*. And writing closures is error-prone—a slip of the keys and you've written `{ 0 }` or `{ 40 }` instead of `{ $0 }`, which look similar and (soon will) work in the same expressions but behave completely differently.
