Octave is unable to parse property validation syntax in class definitions.

Mathworks documentation:
https://www.mathworks.com/help/matlab/matlab_oop/defining-properties.html#mw_4cc53969-cb2c-4fe9-a97e-05e9500f52ba

The following class file causes Octave to give a parse error on the line where
the property type is specified:


classdef testclass
properties
    a = 3
    b double
end
end


This also happens with the older undocumented property validation syntax
(replacing "b double" with "b@double"), discussed here:
