Hello Yigal,
I think that Arrays and AAs need to be removed from the language. I prefer to have a collections framework as part of Phobos without special cases in the language for specific containers.
If it can be assured that all the current array ops will get inlined is all cases and can result in identical asm I'd be willing to consider this.
List!(Foo) list = new Array!(Foo); // instead of Foo[new]
For me to not dislike the idea you would also need to find a cleaner syntax.
