Hi Andrej,

this is just a copy&paste of code from std.range documentation. In fact,
the plain isForwardRange fails. It was just expanded to show where it fails.

Btw, I have this in range.d isForwardRange check:
static assert (is(typeof(r1.save) == R));

Does that mean that the std.range code is wrong?
