[Octave-bug-tracker] [bug #58695] Array is left empty if an element is a function call returning nothing

[Kai Torben Ohlhus]

Follow-up Comment #16, bug #58695 (project octave):

I would favor more Matlab compatibility in this case, too, as pointed out on
the mailing-list.

First I thought this one was fixed alongside with bug #58686, but now I see
the slight difference, if the function has no return value at all, no error is
thrown in some cases.


>> function f1 (), end
>> function f2 (), 1; end
>> f1
>> f2
>> x = f1
error: value on right hand side of assignment is undefined
>> x = f2
error: value on right hand side of assignment is undefined
>> [1, f1, 2]
ans =

   1   2

>> [1, f2, 2]
ans =

   1   2


I want to see errors or warnings if I do stupid things 😊 And assigning
something to an array, where it is impossible to include anything, looks like
a programming error or an undesired/unexpected behavior to me.
