[Ivan Levkivskyi]

I should clarify why I would like to have the possibility to easily compose
functions.
I am a physicist (not a real programmer), and in my code I often compose
functions.

To do this I need to write something like

def new_func(x):
    return f(g(h(x)))

This means I see f(g(h())) quite often and I would prefer to see f @ g @ h
instead.
