Improve implicit partial application

[shilkazx]

Allow multiple reference of implicit partial.
What we can do is:

>>> [0, 1] |> .[1]
1

But we can't do this:

>>> [0, 1] |> .[1] + .[0]
 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'operator.itemgetter' and 'operator.itemgetter'

A nagging crossover could work, but why not improve the implicit partial:

>>> [0, 1] |> =>_[1] + _[0]
1

Implicit partials are intended to be for simple, straightforward operations that can't easily be built out of other operations, not to replace lambdas completely. That being said, Coconut does actually have an easy way to write this without using a lambda (this style is known as point-free programming) using the lift built-in:

>>> [0, 1] |> lift(+)(.[1], .[0])
1

or:

>>> [0, 1] |> .[1] `lift(+)` .[0]
1

Oh, it does implement the feature but using 'lift' under such circumstances is weirder and more cumbersome than implicit lambda.
Anyway, thanks for your good advice and I really love coconut.
