The following currently does not work (gives an ArrayBoundsError.)

 struct A

 void main()

   A[int] a;

 }

But is it reasonable to expect it to work? Should assigning a value to a struct
member be enough to consider the struct an rvalue, thus adding it to the AA?
What about calling struct members?

I think you have to first assign a struct to the array element, i.e.

A[int] a;
A anA;
a[10]=anA;
a[10].i=20;

This works.

I agree with you that assigning a value to a struct member should add 
the struct to the AA, however I'm skeptical about allowing somebody to 
call a member function.

The trouble, of course, is that your think, which looks like an 
assignment, might actually be calling a property.  Hmmm....

I think allowing both assigning to variables and to properties should be enough
to consider the struct an rvalue. Compare it to arrays, the following runs
without error:








but I currently cannot make my own structs work in the same way. Both
assignments fail for a custom struct with length and opCatAssign.

As I know only opIndexAssign inserts new element if it does not exists 
yet, but not opIndex. In your snipet opIndex was called.
