Adding a notation to access argument

[Hiroyuki Fudaba]

Hi all,

In Clojure's anonymous function notation, arguments can be accessed by %, %& or %integer.

For example, it can access to an nth argument by %n.

However, there are some situations you want to access the first item of first arguments, and so on.

This can be done by writing like:

```

#((let [x (first %1)] ... x ...) ...)

```

But this may be better if we could write it more shortly, as follows

```

#(... %1.1 ...)

```

I wonder how people think about the idea.

Any suggestions and comments are welcome!

Thanks! :)

You can use destructuring for that.

Use destructuring, as follows:

```

#((let [[x & xs] %1] ... x ...) ...)

```
