/**
* @assertion If m is marked async*, then:
* • It is a dynamic error if the class of o does not implement Stream.
* Otherwise
* • For each element x of o:
* – If the stream u associated with m has been paused, then execution
* of m is suspended until u is resumed or canceled.
* – If the stream u associated with m has been canceled, then let c be
* the finally clause of the innermost enclosing try-finally statement, if any.
* If c is defined, let h be the handler induced by c. If h is defined,
* control is transferred to h. If h is undefined, the immediately enclosing
* function terminates.
* – Otherwise, x is added to the stream associated with m in the order
* it appears in o. The function m may suspend.
* • If the stream o is done, execution of s is complete.
*
* @description Check that dynamic error occurs if the class of o does not
* implement Stream.
*
* @issue #25634 - the test assumes that dynamic error is added to the stream.
