alt Hacker NewsI don't quite get the problem this tries to solve.
I'm not quite sure that the bug list is the integral part of the source code. And there are dedicated systems that work just fine.
And if I really feel like tagging bug tracker along with my code, I could use any of those systems as long as they support file based databases, like sqlite, or simply static text files for that matter.
There is a certain appeal to not depending on more tools, and there is something elegant about the bug list traveling with revisions, if they are closed when the bug is fixed. So at any point you could go backwards and see known bugs at the time.
This also applies to certain project management flows and statuses.
