is an attribute which specifies that all arguments to a function are not to be modified or looked at in any way in the process of evaluation.
- By setting the attribute HoldAllComplete you can effectively shield the arguments of a function from all aspects of the standard Mathematica evaluation process.
- HoldAllComplete not only prevents arguments from being evaluated, but also prevents Sequence objects from being flattened, Unevaluated wrappers from being stripped, and upvalues associated with arguments from being used.
- Evaluate cannot be used to override HoldAllComplete.
