Checking .empty() covered all of my uses cases. I think... :)
void foo(string s) {
import std.array;
assert(s.empty);
}
void main() {
// Literal null
foo(null);
// Zero-length and pointing at '\0'
foo("");
// Fresh
string a;
foo(a);
// Shrunk
string b = "hello";
b.length = 0;
assert(b.ptr !is null);
foo(b);
}
