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)).

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

The typical equivalences should hold, of course, e.g.
m[1:5][1] == m[2] etc.
