entire file back (__setitem__). The files are expected to be as big as
600 KB which will be appended 30 bytes at a time about 3 times a
second. Performance-wise the system would probably work without open
(..., 'ab') but it would be a real thrashing so the current solution
uses a method "AddTo" as Robert suggested, sacrificing the neat
getitem/setitem syntax.
Just so I don't leave out any information, I actually also made a
DirectoryDict for having multiple 'tables'. In this DictMixin, keys
are directory names and values are FilesDict instances. So to write
"European or African" to the file "/root/tmp/velocity" one would be
just:
>>> d = DirectoryDict("/root")
>>> d["tmp"]["velocity"] = "European or African"
So now I hope it's clearer why and how I wanted a special
__item_iadd__ for the dictionary syntax,

I'd like to build a database wrapper using DictMixin and allow items
to be appended by my own code. The problem is += is always understood
as setitem and getitem plainly.
d = MyDict()
d['a'] = 1
# this is the problem code that's I'd like to override. It's always
setitem('a', getitem('a') + 3)
d['
