I would be against any meaningful name because it will look too much
like a function and people will be trying to use (...) instead of
[...] with it.  A single-letter identifier will look more like syntax
and the concatenator is really just a clever way to take advantage of
Python syntax that recognizes slices inside [].  Novices may just
think that something like c[1:3,9:20]
is an array literal like r"xyz" for raw strings (another argument against "r"!).
