May be the answer...


According to the way how Streams are done in VW, it is a normal 
behavior.
There is an EndOfStreamNotification exception rised when the text 
stream (containing the source code) is read by the parser.

to show this, just do a [Compiler evaluate:'1'] on: Exception do: [ :ex 
| ex inspect. -1 ]
