The bottom line is that you can't put try/catch everywhere, and especially (and
unfortunately) considering the performance hit it represent. What I'm
interested in building is a way to trap unexpected errors and send it
automatically with details, user agent, stack trace etc to a backend
application in order to learn about bugs users will never report and help have
an idea of their frequency.

I don't see another way than a top-level error handler to do that, and
unfortunately, there's not a realistic way to put all one's code and framework
within one global function that would wrap every lines of code in one
try/catch.
