Yup. Though I think WebIDL will take care of the handling for when the
author specifies a negative value. I.e. WebIDL will specify what
exception to throw, so we don't need to. Similar to how WebIDL
specifies what exception to throw if the author specifies too few
parameters, or parameters of the wrong type.
