$Post = Developer`PackedArrayForm is pretty useful. Thanks!

I think On["Packing"] may be one of the most useful things I've come across on this site. Thanks!

As of version 7, one may use On["Packing"] as an alternative to SetSystemOptions[PackedArrayOptions->UnpackMessage->True]. Also, AppendTo will not be appreciably faster for packed arrays in most cases because the great bulk of its runtime consists of copying the array. At least this is done without unpacking unless absolutely necessary (therefore probably using optimized memcpy).
