| 2 # - IOBinding.open() replaces the current window with the opened file, | |
| 3 # if the current window is both unmodified and unnamed | |
| 4 # - IOBinding.loadfile() interprets Windows, UNIX, and Macintosh | |
| 5 # end-of-line conventions, instead of relying on the standard library, | |
| 6 # which will only understand the local convention. | |
