Yeah, I guess that's one way to look at it.  In C, array indexing,
addition, multiplication, and many other commonly-used features
are all unsafe.  In the original K&R C, even function calls were
unsafe, but fortunately they (mostly) fixed that.

To be fair, pointer dereferencing is unsafe in both Ada and C,
so the feature I was asking for ("find all usage of unsafe features")
wouldn't work very well even in Ada -- too many false alarms.
Pointer dereferencing could be made safe.
