There's no problem with representing it as data; just like elsewhere
in Python, you can break out a subexpression and give it a name.

(a @ b @ c)(x)
# <=>
f = (a @ b @ c)
f(x)

It's no different from method calls:

sys.stdout.write("Hello, world!\n")
# <=>
write = sys.stdout.write
write("Hello, world!\n")
