14  * Completion node build by the parser in any case it was intending to
15  * reduce a explicit constructor call containing the cursor.
16  * e.g.
17  *
18  * class X {
19  * X() {
20  * this(1, 2, [cursor]
21  * }
22  * }
23  *
24  * ---> class X {
25  * X() {
26  * <CompleteOnExplicitConstructorCall:this(1, 2)>
27  * }
28  * }
29  *
30  * The source range is always of length 0.
31  * The arguments of the constructor call are all the arguments defined
32  * before the cursor.
