Try ub[0].length = 3. You are trying to change the length on

yes, right these compile. I was surpised it wouldn't accept the
append with just an int.
int[1][][1] ubb;
ubb[0].length = 3;
ubb[0] ~= [5];
If you had more than 1 as a static dimension, then you would
have to change the length of *each* of the elements.
Arrays in D, are actually quite simple. Any time you see:
T[]
It's a dynamic array of T. Any time you see:
T[N]
Where N is a compile-time integer, it's a static array of T.
So dissecting your type:
int[1][][1]
So the outer-most T is int[1][]. You have a single instance of
this, in a static array.
At the next level, T is int[1], where you have a dynamic array
of these.
Finally, at the 3rd level, T is int, you have a single element
in a static array of int.
