I know that people complain. But most of them are unable to explain why
it is a problem.
Plus, hello world size is a very stupid exemple accroding to me. It is
just like comparaing sorting algorithms with an array of 5 elements. The
code bloat that Exception would add is in O(1). So it will get
irrevealant in every non trivial program toy like hello world.
Note that Hello World in Java is about 50Mb. It is because the stdlib is
big. And it has much more played in favor of java than against. Plus, we
consider adding perfect GC (or at least on heap), which would be O(n) on
the code bloat. This may be not noticeable on an hello world program,
but this will sure generate more code bloat on any real application.
