This interface will require some knowledge about VaraidicOperatorMatcherInterface (from D1427) to support that impl.
It will be something like:
  virtual const DynTypedMatcher *constructFromVariadic(ArrayRef<const DynTypedMatcher*>,VariadicOperatorFunction) const = 0;
and will only be used by the variadic impl of Payload.
