There is a proposal [1] (with implemented revision) to implement zero-initialising versions of malloc{,Bytes,Array,Array0}

The benefit is that you can allocate required amount of memory and be certain that it will be cleared (set with zeroes) before you use it.
+1
(Fwiw, it's not only a convenient combined operation but it also has potentially less overhead by requiring only a single FFI-call to calloc(3), instead of having to FFI-call twice into libc when doing malloc(3)+memset(3))
