I never got the point of not having bounds checking in C and its ilk.
C hardly even has arrays.
Yes I know, another broken design decision.
Looking at C's decisions from our perspective is a bit unfair. The only
really unforgivable one, from the perspective of the times when it was
designed, is the one where arrays decay to pointers when passing them to
functions. This completely defeats any attempt at detecting array
overflows.
I don't consider unfair, because there were systems languages at the
time like PL/I and Mesa that had bounds checking.
C designers explicitly decided against it, with the thought that
developers would use lint alongside C, which even today very few do.
