int a = [ 3, 7, 9 ];
1) a = ;
2) a = null;
sets both the .ptr property of the array to null, and the length
3) a.length = 0;
just sets the length to 0.
If all the above is correct, does this mean we should just stick
to either of the first two forms and never use 3). Maybe my
question is when would be want to use 3) without also adjusting
the .ptr ?
