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);
	}
