ShouldCallSuperMethod

package metaobjectTest


@doc{*
  Metaobject 'shouldCallSuperMethod' is an action function. Its 
  associated metaobject declares a method 'eval' that may be 
  called by other metaobjects. It cannot be associated to 
  an annotation:
        // compile-time error
        @shouldCallSuperMethod
        
  This action function can be called by method 'call:' of
  Myan or Tyan (interpreted Cyan) or by the following 
  statements:
         WrEnv env = compiler.getEnv();
         IActionFunction f = env.searchActionFunction("shouldCallSuperMethod");
         f.eval(input);
         
  'input' is a saci.Tuple6 (saci is a Cyan Compiler package) whose elements 
  are:
    - the compiler passed as parameter to a metaobject method
    - the metaobject
    - the list of annotation parameters
    - a symbol to be used if there is an error
    - the current method
    - the environment
    
  All of these parameters are automatically passed when using method
  'call:' of Myan or Tyan, as in the example of annotation 'onOverride'
  below.
