Functions as first-class objects

[Alejandro Reimondo <aleReimondo@...>]

Hi,

Is it possible to send messages to functions?

I need to extend functions as first-class objects.

With string values the feature is implemented

extending string's metatables.

I coudn´t found a similar way to do it with

 function values.

Is it a limitation for functions in Lua?

Any help and/or links to find a solution will be appreciated.

cheers,

Ale
