If there are no objections in the next 24 hours, I plan to merge my "feature/debugger-statement" branch that adds a "debugger" statement to ActionScript similar to the one available in JS.
Use of the debugger statement is completely optional, but it's a useful way to trigger the debugger from code in a cross-platform way. In other words, the following code will just work whether you're running the generated JS or SWF: if(x > 100) { debugger; } - Josh
