+The name get_stop_token denotes a query object[.](#2.sentence-1)
+
+For a subexpression env,get_stop_token(env) is expression-equivalent to:

+- [(2.1)](#2.1)
+
+  *MANDATE-NOTHROW*(*AS-CONST*(env).query(get_stop_token)) if that expression is well-formed[.](#2.1.sentence-1)
+  *Mandates*: The type of the expression above satisfies [stoppable_token](stoptoken.concepts#concept:stoppable_token "32.3.3 Stop token concepts [stoptoken.concepts]")[.](#2.1.sentence-2)

+- [(2.2)](#2.2)
