PyStack can't just rely on being able to call Python code to get you this string. Manually here means that it needs to know that a list in Python release a bunch of pointers that are going to buffer, and the buffer is a bunch of pi objects - every object can be different. So obviously this means that we cannot print all objects. But for most of the common types, dictionary sets, integral floats, et cetera, we functions, all these things. We actually are able to print it. And if most of the time, it's just this built-in types like lists or things like that, then it's going to be very useful and it's going
