We both feel that this would simplify D, make it more flexible, and remove some awkward corner cases like the inability to say a.length++.
How would this remove this corner case?
What do you think?
Whether T[new] is bultin (mostly implemented in the runtime), or a library type (implemented in Phobos) doesn't make much a difference; it's pretty much the same, isn't it? I don't understand what the exact reasons for this decision.
If anything, the array type should be available without additional Phobos imports (i.e. it should be declared in object.d). Ease of access and ease of use is the key thing here.
