Yes, the return value of fetch() is Value. Functions can only have one
return type, after all - fetch() can't return a different thing for
each type you can store.
Call stringValue() on the Value you get back:
String html_page = r.fetch("RESULT").stringValue();
The manual section on store and fetch doesn't explicitly mention this,
but I think it follows from the declaration of fetch() and the section
about the Value class.
