I should clarify that. If you write C style code in D, yes, your code is not 
verifiably safe and hence your programs could be susceptible to malicious 
attacks based on buffer overflow exploits.

But, if you write in D style, using arrays, ranges, and other safe data 
structures, the risk of your program being vulnerable to such exploits is 
reduced enormously.
