Does this mean that I can write

    with file := open('filename'):
        data = file.read()
instead of

    with open('filename') as file:
        data = file.read()
I don't know how I feel about this.

Exactly. Using "as" everywhere might require some small backward incompatible changes to make sure semantics line up, but at least then we wouldn't have redundant syntax.
