This code works:

import std.typecons: Typedef;
alias Typedef!(int[]) MyArray;
void main() {
    MyArray arr;
    arr.length = 10;
    arr[] = 0;
}


While this:


import std.typecons: Typedef;
alias Typedef!(ubyte[]) MyArray;
void main() {
    MyArray arr;
    arr.length = 10;
    arr[] = 0;
}



Gives (dmd 2.062alpha):

...\dmd2\src\phobos\std\typecons.d(2811): Error: cannot implicitly convert
expression (v) of type int to ubyte[]
temp.d(6): Error: template instance std.typecons.Typedef!(ubyte[],
null).Typedef.Proxy!(Typedef_payload).opSliceAssign!(Typedef!(ubyte[], null),
int) error instantiating
