I think Lua is more pragmatic than that. There are important differences in efficiency between functions and tables: arguments and local variables are more efficient than table entries. This is not just an artefact of the implementation: LuaJIT's analyses rely on the restrictions on how you can use local variables (without going through the debug library) such as not being able to enumerate them like a table and not being able to get or set them via a dynamically computed name.
If you want a language that uses the same structures for tables and functions, see Python.
Tony.
