{code} macro executes velocity code now

On the http://www.xwiki.org/xwiki/bin/view/Code/ListAllSpacesSnippet page, the following code below is executed instead of being escaped. This was working fine at least in Beta 1 when I created that page. It started failing in beta 2 or beta 3.

{code}
#set($spaces = $xwiki.spaces)
#foreach($space in $spaces)
* [$space>${space}.WebHome]
#end
{code}

Am I missing something? Is it normal that it's not escaped anymore?
