I do think that professional tools can help dynamic languages consolidate the ground they've been gaining. And to that end, conventional capabilities -- such as suport for testing, debugging, and version control -- will be prerequisites. But dynamic languages really are different in important ways, and their tools should be as well. It's time for some fresh thinking on this topic, and for some new approaches.

Jon also mentions DSLs, stratified design and Patrick Logan (who used to post here more often, and will be welcomed back should he choose to return...)
