There are good reasons why a “view” should not be its iterator.

you’re right, but one would expect the view’s __getitem__(i) method to
return the ith grapheme, which implies constant-time access. and we can
only support linear-time access to that (i.e. by iterating stuff) if we
don’t want to build a complex index.

so should we do a view object that only allows something like my
find_grapheme and iteration?
