The inspector is so cool because one can get feedback for each step. I was working with a text list, and going in very small steps because I wasn't quite sure what I wanted to do, so I:
1. Pasted into playground:
'lineOne
...
lastLine'
cmd-g
2. self lines sort
cmd-g
3. self asSet asOrderedCollection sort
Then I thought (although the above is a bad example for this), since GT encourages to take these small steps, it would be cool to have a command to assemble the code from all the workspaces into one statement, so 1, 2, and 3 above would become: "aString lines sort asSet asOrderedCollection sort". Again, not a great example, but I know this would've been useful other times...
Cheers,
