+# Why to_bufferable?
+# Python 3 is very different from Python 2.x when it comes to strings of text
+# and strings of bytes; in Python 3, strings of bytes do not exist, instead to
+# represent arbitrary binary data, we must use the "bytes" object. This method
+# ensures the object behaves as we need it to.
