BUILT-IN MATHEMATICA SYMBOL

HoldAll

HoldAll
is an attribute which specifies that all arguments to a function are to be maintained in an unevaluated form.

Details Details

You can use Evaluate to evaluate the arguments of a HoldAll function in a controlled way.
Even when a function has attribute HoldAll, Sequence objects that appear in its arguments are still by default flattened, Unevaluated wrappers are stripped, and upvalues associated with the arguments are used.
