RE: Function Pointers?

["Eric Ries" <eries@...>]

Just like you are doing, except without the first set of () around do_cmd1,
etc.

So, just to be clear:

function foo()
-- do something
end

myTable = { foofunc = foo,
 		barfunc = function ()
				-- do something else
			    end
	    }

myTable now has two "function pointers" that you can use like this:

local a = myTable.foofunc
local result = a()
local b = myTable.barfunc
local result2 = b()
