Patrick opened my eyes to the fact that we'd like the function body here, not the name only. The reason I keep forgetting about it is that it is lame. In Chromium, we have a link to the source code with the handler function for each event listener instead. I think JSC should catch up soonish. But neither toString nor displayName would fix the problem of navigating to the proper function in case of bind.

I think what we should do is to instrument all the handler registrations and store JavaScript source location at the place of the registration. That clearly adds some overhead and needs to be optional, but it gives us source location of the handler registration. And that is exactly what user needs. He might see call to bind there, but he will see bind's arguments as well. We were thinking of doing this for timeline long ago. It might be good time to start.
