Thread Subject: visibility of classdef subfunctions

This issue came up in another thread, but it piqued my curiosity.

It seems that subfunctions in a classdef file are visible to class properties and methods, but for some reason they are not visible in the classdef Attributes block. I'm wondering if this is intentional or a bug.

EXAMPLE:

classdef myClass

   properties
     prop=initialize;
   end
   
   methods
       function out=myfunc(obj)
           out=initialize;
       end
   end
end

function out=initialize();%appears in myClass.m

  out=true;
 
end

%%%%%%%%

This works fine

>> clear classes; A=myClass; A.prop, A.myfunc,

ans =

     1


ans =

     1


However, if I add a class Attribute block

classdef (Sealed=initialize) myClass

then instantiating the class causes an error.
>> clear classes; A=myClass;
??? Error using ==> myClass
Error: File: myClass.m Line: 1 Column: 11
Undefined function or variable 'initialize'.

This problem goes away if I relocate initialize() to its own separate M-file, but I'm wondering why this would be necessary.

The initial reaction is that this is a bug. Further investigation will determine if it is fixable or will become a "feature"
