There is less concern with (compiler-provided) safety, and more with
speed. The C++ philosophy is "if you don't need it, you don't pay for
it." For example, you don't take a (potential) performance hit for
exceptions or range-checking, unless you explicitly use them. The C++
committee would rather (I surmise) define an interface that maps
easily to existing systems as a light wrapper, than one that is harder
to implement but much safer. I don't think one way is better than the
other. It depends on your needs. I use both languages extensive where
I work.
