(defmacro short-fn
```
Shorthand for `fn`. Arguments are given as `$n`, where `n` is the 0-indexed
argument of the function. `$` is also an alias for the first (index 0) argument.
The `$&` symbol will make the anonymous function variadic if it appears in the
body of the function, and can be combined with positional arguments.
Example usage:
(short-fn (+ $ $)) # A function that doubles its arguments.
(short-fn (string $0 $1)) # accepting multiple args.
|(+ $ $) # use pipe reader macro for terse function literals.
|(+ $&) # variadic functions
