What would be great in 2.5

Is if someone could come up with a way to keep WP from reformatting any code you put in to your post. I.E. if you want to run a little JAVA, and don’t want to worry about it getting “WP Texturized” or reformatted or in anyway molested BECAUSE ITS CODE AND IT DOESN’T LIKE BEING MOLESTED would be sweet. Like a “run this code – don’t screw with it”

Unless there is some way to do that in 2.3.3 that I don’t know about…
