Subject: $SAFE block?

Once $SAFE is set to a certain level, it's not possible to lower it again. As 
far as I know, the only way to execute some code at a high $SAFE level and 
then return to a lower one is like this:

thread = Thread.new {
	$SAFE = 4
	# .. do code
}
thread.join

Which is messy to say the least. Why not have something like:

Kernel#safe(anInteger) { block }

Or even:

Kernel#eval_safe(aString, anInteger)

Although this could probably be written in terms of the first one.

Is there something like this already? If not, why not?
