Is it an optimization?

[Max Ischenko <max@...>]

I'm using the following function:

function foobar()
	local s = ''
	-- lengthy computation and printing report to s
	local t = {text=s}
	function foobar()
		return %t.text
	end
	return s
end

The purpose of rewriting the function is to use value computed in the
first call. It works just fine. 

The question -- will GC be able to freed
old contents of the foobar? Doesn't %t ref. disables it?
