I use "it" sparingly myself for that reason, but -- perhaps based more 
on my own ignorant superstitions than anything actually happening in the 
engine (Fraser, care to chime in?) -- my hunch is that since "it" is 
already initialized using it saves an additional malloc.

Over the scope of an entire code base this habit might save me as much 
as two milliseconds. :)
