display is useful for seeing the intermediate results of a function as it runs. It's tiresome to clutter our programs with calls to display, though. A way to log the inputs and outputs of a function would be nice.
Define the function debug1, which takes a function argument f and returns a function that, when called, writes its input and output to the console, and returns the same thing f would have when called. In other words, the type of debug1 is (x -> y) -> (x -> y).

We were introduced to OOP this week. While it may seem very complex, at heart it's still about the same notions of data and operations on data.
As JediScript has a rather complicated OOP system with many moving parts, it's important to distinguish the ideas from the implementation.
State and behaviour: Objects comprise state and behaviour. Programs are no longer structured around just functions, but around a central object which specific functions operate on. Computation usually involves updating the state of that central object over time.
Aggregation: As with functions, we can compose objects, building large objects out of smaller ones.
Definition: Important to keep in mind! Will help you reason about streams and guide you when you get confused.
Wishful thinking: Useful strategy for thinking about recursion and infinite things. Basically you assume that the function you are writing already has a correct implementation, and you use that assumption to write its recursive case. Keeping the return type of the function in mind can help.
Infinity: Streams can be finite or infinite.
Some functions can only deal with finite streams, for example stream_length and stream_append (first argument should be finite). They need to evaluate an entire stream to have an effect.
