Currently this is not allowed, but do you desire a feature like this? struct Foo { int x, y; int[100] array; } void main() { auto foos = new Foo[100]; foos[].y += 10; // *** } Bye, bearophile |

An interesting use case:
void main()
{
cdouble[100] foos;
foos[].re = 5.0;
}

I don't often have to update arrays of complex numbers, more often I have to set or update a single field of an array of structs.

In fact, I would be more interested in the opposite :
void main() {
auto foos = new Foo[100];
auto ints = new int[100]
ints = foos[].y;
}
This would simplify the wrinting of numerous application, especially in the writing of image/video processing (eg. rgb2yuv conversions) This would also simplify the writing of template library transforming "array of struct" to "struct of arrays" in a transparent manner for the library user.

If you allow that syntax on the left you probably allow it on the right too.
