+The pretty printer will just setup closures that will extract the underlying stream
 object from a pprint-wrapped stream, and invoke its low-level functions. If pprint wrapping isn't present,
 the slots will contain closures that directly invoke low-level functions of streams. Gray streams will
 still replace the stream functions, because it's capable of invoking the replaced functions.
 
+In addition to these changes, it is planned that the stream function primitives will be moved from the Stream
+java class to a streamfunctions library, allowing the stream functions to be written in lisp rather than java.
+There's an ongoing aspiration to increase the lisp/java code ratio of ABCL, and this new design allows for that.
