Getting local variable debug info from within a nested function.

["Matthew Armstrong" <turkeypotpie@...>]

So I've gone and written myself some debugging utility functions, but am running into some trouble with the following:

function outer(param)
    return 
        function()
            -- (do something with param)
            debug.debug()
        end
end

outer(42)()

So when I break at debug.debug, a search up the stack doesn't give me any info about param.  Any way to get this?
