So of course by now we all know this works, and pretty easily too.
(Check out a plain 4.5 image and you'll see.)

What I find interesting in Phexample, and Gilad Bracha's "debug mode
is the only mode", and Lightable, and Bret Victor's demo, is... it's
all old news!

http://www.subtextual.org/OOPSLA04.pdf - "Example Centric Programming"
by Jonathan Edwards - describe's Lightable's instarepl (*) on the
first page! And it was written nearly a decade ago!

(*) It's a two-pane screen. On the left is something a lot like a
Smalltalk Workspace - you write in your Clojure forms. On the right is
a pane that evaluates those forms as you type, printing their output.
So when you have only written "(+ 3 4" nothing happens, but as soon as
you complete the form with a ")", the right pane immediately displays
"=> 7". Even for someone used to a live environment (me), that was
startlingly enjoyable.
