Syntax
with referents-not-allowed (with open-modifier (& open-modifier))+ | with open-modifier)*
This open modifier is the default for most streams. It does not allow referents to be attached to the stream, and any attempt to write a referent to the stream is a fatal error, regardless of whether the referent has a current value.
The only streams for which this modifier is not the default are:
