What about using forward ranges and take?

        // String version: can slice
        Take!T readUntil(isAtEndPredicate, T)(ref T input) if(isForwardRange!T) 
{
                auto savedInput = input;
                size_t n = 0;
                while (!input.empty && isAtEndPredicate(input.front)) {
                        input.popFront();
                        n++;
                }
                return take(savedInput,n);
        }
