[Octave-bug-tracker] [bug #59704] function call on classdef subobject fails with "numel: invalid return value"

[Fernando]

Follow-up Comment #3, bug #59704 (project octave):

I also wonder if it is correct to call the overloaded numel method here to get
the number of outputs of the sentence.

If we modify the bug59704/numel method to return the value 2, we would have:


>> o=bug59704();
>> o.p
ans = [](0x0)
>> [o.p]=size(rand(2,5))
o =
  bug59704 object with properties:
      p: [1x2 cs-list]
>> o.p
ans = 2
ans = 5


Initially, o.p is an empty array. However, when used as an lvalue, it acts as 
a cs-list of two elements (because the numel method returned 2). As a result,
o.p ends up storing a cs-list. Is that behavior correct? I thought cs-lists
could not be stored in a variable.
