IMHO no.

It's better to use `.length` to test if an array is empty. Why ? 
Because the day you'll have a function whose parameter is a 
pointer to an array, comparing to null will become completly 
confusing:

---
void whyPeopleShouldUseLength(char[]* buffptr)
{
     if (buffptr != null && buffptr.length > 0) {}
}
---

Here you really have to test if the variable is assigned, it's 
not a shortcut to test the internal buffptr `.ptr` member.
