For the "reiterable" cases like dictionary views (where the object is
not consumed), an appropriate __str__ or __repr__ should be written).
Whether that is something as simple as "<repr of underlying
dict>.items()" for an items view, or something more complicated that
more directly shows the content of the view, I'm not sure.
For the standard iterators like enumerate and ranged, I would suggest
that they be modified to use a repr of the form:
"reversed(<repr of underlying iterable>)"
"enumerate(<repr of underlying iterable>)"
"iter(<repr of underlying sequence>)"
"iter(<repr of callable>, <repr of sentinel value>)"
While those obviously won't show how much of the iterable has been
consumed, neither do the current representations.
Cheers,
Nick.
