Boy are people getting more and more sure of compiler technologies these
days.  I'm not so overly confident especially as languages that started
simple like C continue to get more elaborate with each new standards
release.

But please name any compiler that will automatically not generate a
return statement at the end of a function.

I don't know how the PIC compilers handle automatic variables but they
are 'created' and 'destroyed' at the beginning and end of a function so
would there be unreachable code put in to fix the 'stack' as well?

And these compilers, which are indeed getting better at many things but
with much angst along the way, could use such a construct to generate
warnings and/or errors for simple things like a return statement in the
function of a path to the end of the function.
