Don't agree here: this is the standard way to do it, look for example at os.getenv (took python 2.7 API because it uses nearly the same theme as Blender API doc).

Yes I know, but for me it looks ugly. Maybe it is better to remove the square bracket. I looked into the Blender API and I don't find any methods which are using square bracket for optional arguments.
I think it is better to ask Campbell.

Sorry, I answered but forgot to submit my answer... :-/

I actually discussed with Campbell, and he told me that in Blender the "defaults" solution is in use rather than the "square brackets" one. My last diff shows that change.

Sorry again for the inconvenience.

Yes, I know, but lists aren't supported into arguments AFAIK (look at the compiled doc for 2.74 -> nothing shown). The only way I found was to make a simple list, even if horizontal. But I'd be very happy to find a way to make vertical lists...

Filter for levels calculations. Each output color component is obtained as follows:

* Otherwise it is linearly extrapoled between 0 and 255 in the (min, max) interval.

You can use the characters R, G, B for the 3 color channels, A for the alpha channel, :class:`ImageBuff`,
0 to force a fixed 0 color channel and 1 to force a fixed 255 color channel. :class:`ImageMix`,
Example: "BGR" will return 3 bytes per pixel with the Blue, Green and Red channels in that order. :class:`ImageRender`,
"RGB1" will return 4 bytes per pixel with the Red, Green, Blue channels in that order and the alpha channel forced to 255. :class:`ImageMirror`,
A special mode "F" allows to return the image as an array of float. This mode should only be used to retrieve :class:`ImageViewport`
