function invocation failing test

Is there any interest in supporting a shorthand for invoking methods on an entire array/object?

Something like:

```coffeescript
items..foo()
```

Which would translate to something like:

```coffeescript
item.foo() for item in items
```

Or perhaps something that worked within array comprehentions, except lacking an iterator:

```coffeescript
..foo() for items
..foo() for items by 2
for items ..foo()
for items by 2 ..foo()
```

I feel like it's one of the most common patterns in programming, an a prime candidate for some sugar. I haven't implemented it but I would like to hear some feedback about whether it would be worth the effort.
