dnspies:
What about if I have a 2D array (ie int[][]) and I want to
append an empty int[] on the end? Will this work?
int[][] nested;
nested ~= null;
~ is overloaded, so how does it know what type I intend null to
be? How can I specify it?
You can increase by one of the length of the outer array, or you
can append an empty one:
nested.length++;
or:
nested ~= [];
I don't remember if you can also append a null. Appending a null,
if it works, could be more efficient. Take a look at the ASM.
