If you're going to delete it anyway, and the length is a compile-time 
constant, you might as well pass a static array from the second function 
to the first instead.

Another option:
---
int func(int[] g = null) {
     g.length = 10;
     // original function code goes here
}

If a sufficiently-sized buffer is passed in, it's used. If not, a buffer 
is allocated. The main benefit over the 2-function approach is that only 
a single function is needed (so less clutter), but it does still 
heap-allocate when a new buffer is needed (and it doesn't delete such 
newly-allocated buffers).
