Feature or enhancement

Standard lists accept clear as a shortcut for del xs[:]

xs = ['a']
xs.clear()

However, multiprocessing.ListProxy omitted support for clear().

from multiprocessing import Manager

with Manager() as manager:
    xs = manager.list()
    xs.clear()

raises the following exception

AttributeError: 'ListProxy' object has no attribute 'clear'

Pitch

If clear is supported in a standard list, it should be supported in a multiprocessing list!
