Hm. Interesting discussion. What do you think about python like
strategy? That said,
application always dump backtrace when any unexpected thing was happen and
application user (not app creator) see it. At this time, current frame
is most useful
information.

I'm not sure there is such application in real world. _I_ only uses
backtrace() for debugging.
I only says I'm not sure every people use it for only debugging.

thanks.
