I did see that and it is distressing! Perhaps it’s a good thing nobody ever uses them. :)

I’m not sure if you caught Grant Skinner’s slides on performance, but his tests show that using var $graphics:Graphics = object.graphics is 10x faster than “with” blocks. http://gskinner.com/talks/quick/#58

Wow, that is surprising. It seems like such an innocent feature that it would be hard to make a memory leak out of it. Thanks for this tip, I’ll have to look into it further.

I used to use With blocks when drawing graphics, but pinpointed them as the source of a major memory sponge. The profiler said my graphics class had thousands of instances within seconds, when there were only a dozen constructed. I replaced the With block with everything typed out and that fixed the issue. I just accepted it and moved on, but it still puzzles me.
