and be turning it into something like

template foo(alias pred)
    if(testPred!pred)
{
    auto foo(R)(R r)
        if(isInputRange!R && !isForwardRange!R)
    {}

    auto foo(R)(R r)
        if(isForwardRange!R)
    {}
}

The example(s) is confusing me. `foo!(first)(second);` isn't really an alternative to `foo(first, second);`. Am I misreading something?
