buildIn: composer composer tabulator with: [:t | t ... ]
The old way still works, of course. The nice thing about this solution is that it works better with the editor (you are given the composer).
For a live example, see: http://www.humane-assessment.com/blog/building-a-simple-code-browser
Let me know what you think.
"composer" is a very generic term. Wouldn't "browser" be a better variable name?
