And with it we landed in a world full of buffer overruns and memory errors exploits.

Sure Pascal was a bit of a pain sometimes to use, but it did promote safety.

Now we have to fight an uphill battle with C developers to make them realize
the benefict
of using safer languages while fixing security holes every day.

But Pascal evolved into Modula, Modula 2, Oberon, Delphi, Object Pascal, etc., always trying to find a workable combination of features. Meanwhile, the world passed it by.

See bugs from integer overflows, for example.
A "battle" that I'm willing to "fight" every day :-)

D is a bit better than C in this regard, if you write a short program in C and then you write a similar program in D, you will probably put quite less bugs in the D version (I think in C# you put a bit less bugs than D, because the C# compiler is a little more strict).
