Chris has already answered specific questions, but I wanted to point out the
underlying philosophy:

+ Dylan application code is developed in a separate process from the Dylan
environment.

+ The Dylan environment, in general, can't evaluate Dylan code itself.

+ You use a Dylan listener on a particular application/project rather than
everything loaded into an enviroment (a la Lisp).

+ FD's "listener" is called the "interactor" and is part of the "debugger".

+ FD's "playground" is just a pre-built application containing some interesting
code you might want to interact with.

+ So to use a "listener":
	- create a project 
	- select "Interact" or "Debug" on it

+ FD's listener has some neat features. eg It turns return values from executed
code into selectable items that can be browse.
