Not as readable as a.append(4), which works today and doesn't require
the user to memorise the special case that <<= works on lists but
(presumably) << doesn't.
Or perhaps it would. What would a bare << mean for lists?
b = a << 4
could mean the same as
b = a + 
but we already have a spelling for that, do we really need another one?
