There are actually 4 different default setters:

use variables :D;    # works, e.g. ‘my Int $a = 42’
use attributes :D;   # works, e.g. ‘has Int $.a = 42’
use invocant :D;     # parses, does not work yet, e.g. method a(Int:) {} # Int:D:
use parameters :D;   # parses, does not work yet, e.g. sub a(Int $a) {}  # Int:D
