I still question whether its correct to design a function which requires
this. I thought the idea of encapsulating code inside a function is that
its non-dependent/black-boxed.... still for every rule there is an
exception!

maybe Lars thought his post had disappeared into /dev/null, not
altogether strange considering the fluctuating time delays in posts
being sent out! then maybe he's an impatient s.o.b ;-)

He has a lot of those (excellent posts that is), but he is really giving
an example of debugging not writing code that relies on a debug_ function.

I don't think debug_backtrace() should be used like this, having said
that it will work - but I can only imagine that its a heavy function to
call (because it has to 'analyse' the stack in order to return alot of
info, nearly all of which is not needed in the case Lars presented)
