New Revision: 2470
Log:
NSMutableArray now implements the same public
interface as the builtin list type, as well
as the ObjC interface as well.
The only exception: NSMutableArray.count is the
-count method from ObjC, which is not the same
as list.count.
There is an issue that needs further work: I
had to implement __getslice__ and __setslice__
because slice assignment wouldn't work without them.
This shouldn't be necessary however and causes one
test failure.
(Another reason to implement __getslice__ and
__setslice__ is that the stdlib testcases explicitly
use those methods, but that's easily fixed by either
reimplementing those tests in our suite)
