I thought initially about doing "ec = RangeError" here.
But the same exception must be thrown and stored in the stream.
I still see some value in introducing "RangeError" for other binding code.

I wonder whether we should rename controller methods (enqueue, error and close), in particular error() which may be misleading with m_error getter.

This is messy. Having the same function sometimes set exceptions directly on ExecState and other times indicate the exception with an ExceptionCode is a bad idea.

If you add this new type, I think you need to add handling for it in a few places.

OK

I plan to reuse it in ReadableJSStream::create().
I will also add it in some binding places where the range message is not very meaningful.
