The idea is to introduce new syntax for the list.append() method.

mylist[] = item

For all practical purpose, it would be enough to define that the expression:
mylist += [item]
gets optimized to mylist.append(item).

Unfortunately, that would create yet another special case of operators breaking the rules. Most operators invoke magic methods. This would prevent ``+=`` from invoking ``__iadd__`` for lists, since the right-hand side would need to be compiled differently. It's similar to why ``and`` and ``or`` keywords can't have magic methods.
