[Octave-bug-tracker] [bug #59617] Function handles in argument list impede dispatching to correct class

[Markus Mützel]

Update of bug #59617 (project octave):

              Item Group:           Build Failure => Regression             
                 Release:                   other => 6.1.0                  
        Operating System:               GNU/Linux => Any                    
                 Summary: [octave forge] (interval) Failure in building the
documentation against Octave 6.1 => Function handles in argument list impede
dispatching to correct class

Follow-up Comment #3:

This looks like a regression in core Octave to me.

With the attached @classA in Matlab R2020b:

>> a = classA();
>> max(a,1)
This is classA.max
>> max(1,a)
This is classA.max
>> max(@() 1,a)
This is classA.max
>> max(a, @() 1)
This is classA.max


And in Octave 6.1:

>> A = classA();
>> max(A,1)
This is classA.max
>> max(1,A)
This is classA.max
>> max(@() 1,A)
error: max: cannot compute max (function handle, class)
>> max(A, @() 1)
This is classA.max


This is also a change in behavior with respect to earlier versions of Octave
(see comment #2).
