I know what the Zen says about special cases, but in this case the rules were apparently broken with impunity.
Well, the proposal was to interpret m[i] as m.group(i), for all values of i. I can't see anything confusing with that.
it can quickly become rather confusing if you also interpret m[:] as m.groups(), not to mention if you add len() and arbitrary slicing to the mix. what about m[] and m[i,j,k], btw?
What about them? They aren't supposed to be supported by every object that allows subscript, are they? And why not just not implement len()? As for the [:] <-> groups() issue, [:] would have to be consistent with indexing and return the whole match and the subgroups. (Or, the API could be overhauled completely of course, remember it's Py3k.) Georg
