Ah, right; I misread his proposal as saying that m[:] should return [m[0]] + list(m.groups()) (rather, I expected that m.groups() would include m.group(0)).

match groups are numbered 1..N, not 0..(N-1), in both the API and in the RE syntax (and we don't have much control over the latter).

To answer your first question: it is clearly groups that you want to index, just as the .group() method indexes groups.

so what should len(m) do?
