How to enable Ruby like method chains in wx(Python) shell

In Ruby, everything is an object. Every bit of information and code can be given their own properties and actions as an example below, (https://www.ruby-lang.org/en/about/)

rb> 5.times { print "We *love* Ruby -- it's outrageous!" }

Some of them have criticized Python as an inconsistent language. For example, Python uses mix of method and functions like sum((1,2,3,4j)).real. Ugly? No. Rather, I think, it is flexibility of Python, no inconsistency.

I got an idea to make Python chainable like Ruby. To do that, one and only one quite simple rule was required, as follows;

x @ y => y(x)

Hence, we can chain methods as x @y @z => z(y(x)) I named this rule 'pullback' which comes from mathmatical terminology. Actually, this rule can chain not only the instance method but also ANY functions.

Here shows a simple example:

rb> p 5.times.to_a
[0, 1, 2, 3, 4]

py> 5 @range @list @p
[0, 1, 2, 3, 4]

You may notice that the printing function (p = print) is also chained. I have extended the wx.py.shell to allow chain of the functions as follows:

In the next example, you will see that methods and functions in any modules are chained.

Suppose `buf' is the binary data received from the image server. The input and output-code are like these:

# input:
>>> buf @io.BytesIO @Image.open @np.asarray @plt.imshow; plt.show()

# interpreted as:
==> plt.imshow(np.asarray(Image.open(io.BytesIO(buf)))); plt.show()

Also, note that we are pressing [C-j] (eval-expression) each time we chain to see if the py expression is correct.
