The "bizarre reason" of why we want to debug our code integrated with JS is that we want to take advantage of the huge amount of great javascript UI libraries that are out there. Why would we ignore those and have to reimplement a lot of stuff in Python code? Pyjs can already interface with JS libraries, so I think it is reasonable to also want to debug such code.
I do not want this to get into a flame war about the preferred way to do UI development. But I actually think HTML+CSS+JS libraries (if done right) are a better way to implement a web user interface, compared to a pure GWT approach. To me it always seems that GWT ignores a lot of the advantages that a web UI can have and instead tries to bring everything back to the way apps are written on the desktop. This makes sense if you try to bring Java developers to web development (as was the original goal of Googles GWT), but nowadays there are a lot of great web developers out there that know and understand the browser. Combine that with the huge amount of JS libraries out there and you can rapidly develop great UIs. As to the question of why we don't want to use JS directly: because it leads to hard-to-find bugs (for example, related to its brain dead scoping and handling of closures). I have also seen a tendency for it to produce code that is hard to read and understand for other developers. Python is the complete opposite. It is very hard to write convoluted code in Python and it is in general a very clean and structured language. That is why we chose it for the server side and it would be great to be able to use it for client side code as well. But without source maps I do not think that can happen (at least not with pyjs). @Jim Washington: thank you for the suggestion of Dart. It is one of the options we are looking at.
