Well, I want to offer a more radical proposal: why not free squared
braces from the burden of representing lists at all? It should be
sufficient to write

>>> list()
list()

After being free one can use them for other purposes e.g. replacing the
ugly @ decorator character by the lovely [ .. ] notation or other
important features no one never trusted to implement waiting for the
right syntax sugar. More than this round braces together with lists can
be considered as a concession to the LISP programmer who was repelled
from Python by the decision to eliminate functional programming
features.
