it really depends of your other code. if you don't have any
slices of the array, for example, you can use `a.length = 0;
a.assumeSafeAppend;` -- this will reuse the allocated memory. but
you should be REALLY sure that you have no array slices are
floating around! 'cause you effectively promised the runtime that.
otherwise, `a = [];` and `a = null;` is the same, as `[]` is a
"null array".
most of the time it is ok to use `a = null;` and let GC do it's
work. it is safe, and you'd better stick to that.
