Who said setting an array to null is bad practice? I disagree. null

better way to represent it, because it sets both the ptr and the length

0, while "" only sets the length to 0.
char[] arr = "";
assert(arr == null); // passes
assert(arr is null); // fails
I see, I didn't know this.
BTW, the default value is not part of the function signature, if you want
to in your code use = "", as long as you do the comparison correct, it
should be valid.
