Hello,
I don't understand why the compiler refuses the code below, with the error
__trials__.d(33): found '.' when expecting ';' following statement
(Note that method set returns this.)
class C {
int i,j;
this (int i) {
this.i = i;
}
C set (int j) {
this.j = j;
return this;
}
override string toString () {
return format("C(%s,%s)", i,j);
}
}
void main () {
c = new C(1).set(3); ///////
writeln(c);
}
Well, the example is somewhat artificial, but this idiom is highly useful.
Denis
