Is there a way to do that?
Since the following are both true:
int[] a = null;
int[] b = [];
assert(a is null);
assert(!a.length);
assert(b is null);
assert(!b.length);
What I would like is to tell that b is an empty array and a is a null
array.
No way. `null` and `[]` are the same thing for arrays. (Ulike `""` for
strings which has a non-null `.ptr`.)
You can distinguish `null` from other (non-null, non-`[]`) empty arrays.
For example:
----
int[] b = [1, 2, 3];
b = b[0 .. 0];
assert(b !is null);
assert(!b.length);
----
