[Octave-bug-tracker] [bug #47680] classdef @ operator to overrided superclass methods

[John W. Eaton]

Follow-up Comment #13, bug #47680 (project octave):

OK, maybe there is a better way to handle the parsing than what we are doing
now that would simplify it a bit.

In superclass references and metaclass query expressions, are spaces allowed
between the elements?  Can package names be used ot qualify the class names? 
For example, are any of the following allowed (note spaces)?


obj . method @ superclass
pkg1 . pkg2 . class_name . method @ superclass
? class_name
? pkg1 . pkg2 . class_name


If spaces are allowed, then I think we already get some of these wrong.  And
we try to recognize hings like address@hidden as a single identifier in the
lexer instead of just returning a series of tokends (ID, '@', ID) and
recognizing the syntax in the parser.
