memset_s

[bearophile]

A function+its semantics from C11 that seems good to have in D 
too:

>memset(): The standard guarantees that memset_s will over-write 
>the argument array, even if the optimizer thinks that those 
>stores are "useless," such as when over-writing a password 
>before leaving a function.<
