I agree also.
But to play devil advocate, and using similar argument allready given to us
in this thread, one can reply: as long as the language is defined to behave
this way, it becomes the programmer resposibility, and any unexpected
behaviour resulting from using such language means the programmer is
incompetent.
So, as long as C/C++ is defined not to do array boundary checking (which it is),
then no one has the right to critisize such languages, and incompetent
programmers need to understand this.
And as long as java is defined that it can produce a negative value when
adding 2 positive values, and without *any kind of warning* to the programmer,
then it becomes the resposibility of the programmer to understand this,
and a programmer that produces a program that fails to check everywhere
for this, is an incompetent programmer.
Of course the above argument is all a big ballony, but this is the defense
people are comming up with to justify this. It looks like when a language
is popular, it can do any strange things, and people will still defend it.
