From what I understand, this PR is proposing to add a range 
wrapper that
catches exceptions thrown from range primitives and passes them 
to a
user-specified handler. Seems to be a promising idea, but it's 
probably

It is exactly that:
    auto s = "12,1337z32,54,2,7,9,1z,6,8";

    auto r = s.splitter(',')
        .map!(a => to!int(a))
        .handleBack!(ConvException, (e, r) => 0)
        .array;

    assert(equal(h, [12, 0, 54, 2, 7, 9, 0, 6, 8]));
