digitalmars.D.learn - aa bug?

S[char[]] aa;
void main() {
  aa["test"].i = 10;
}

Error: ArrayBoundsError
D1.046

looks like a bug to me or can't structs be aa's?

But you never inserted anything in aa["test"].

You must do:

S s;
aa["test"] = s;
aa["test"].i = 10;

or:

S s;
s.i = 10;
aa["test"] = s;

erm, ok
Thanks
So no creation on use :)
Personally I find the declation step clutter in the first case.
Maybe promote the bug  to a request?

It won't happen.  The behavior you want *used* to be the AA behavior
but was changed after several years and much complaining.  It's not
going back.

Try:

struct S { int i; }
S[char[]] aa;

void main() {
    aa["test"] = S(10);
}

In theory a Sufficiently Smart Compiler is able to optimize that code well.

struct literals .. need to remember all D's features :)
D1.046 seems SS
aa["test"]=S();
works fine as well


 Try:

 struct S { int i; }
 S[char[]] aa;

 void main() {
    aa["test"] = S(10);
