This doesn't work as expected, I think.
auto r = iota(1,10).withHistory;
writeln(r.front);
writeln(r.front);
Oops. That output should be the same, since popFront hasn't been
called.
I made this mistake in my other ranges as well...
The code's also bad for preserving the entire history when only
the
latest is needed for what it's doing.
