inheritence and base element syntax cookie ?

["Grellier, Thierry" <t-grellier@...>]

-- Hello,

 

-- Lua equivalent to C++:

 

-- #include <iostream>

-- struct C { void m() { std::cout << "C::m()" << std::endl; } };

-- struct D : C {

--   void m() {

--     C::m(); // base class

--     std::cout << "D::m()" << std::endl;

--   }

-- };

-- int main() { D d; d.m(); return 0; }

 

C = { }

 

function C:new( o )

  o = o or { }

  setmetatable(o, self)

  self.__index = self

  return o

end

 

function C:m() print("C:m()") end

 

D = C:new{}

 

function D:m()

  C.m( self )    -- no better OO-like syntax available ? like :C:m() for example ?

  print("D:m()") -– I’d like to clearly express this is different from call to external function
