The compiler will abort() if an exception is not caught. I don't know if the
exception handling code is in the function that calls or in the function
that is called. Note that I'm not at all sure if the above code will lead to
shorter code, as it is mostly for compile-time checking etc. Violations
against the above declaration are possible and in large complex programs
unavoidable.

Exception handling is a powerful feature, and makes other global error
strategies mostly unnecessary. Therefore the size of compiled and well
written C++ programs will not be larger than an equivalent C program. *And*
the source code will be much cleaner, as you don't have to nest if()
statements or such things.
Voting for Exceptions,
