    hey guys!

    what are differences from declaring function in lua between this two:

    1) local dummy = function(x,y,z)

    2) local function dummy(x,y,z)

    are only aesthetic?

    thanks.

      Afaik, there is a small difference when you're using recursion: http://www.lua.org/pil/6.2.html Otherwise, there is no difference between these two.

      Local functions are called faster. Defining these two ways, there is no difference. But I am sure you already had scope problems, that you needed to call function, that was defined BELOW the calling line. To get around this you do this:
      local foo1 
 
function foo2()
    foo1()
end
 
foo1 = function()
  --.....
end
      The document Atilim has linked to explains this under "forward declarations".
