Update of bug #31821 (project octave):

                  Status:                Wont Fix => Fixed                  


Follow-up Comment #8:

Only thing I might do is change the error message.

I added file blah.m in the directory above where I started Octave.

function y = blah ()
  disp ('executing blah');
  y = 5;

Now, I run the following sequence

octave:1> f = @blah
f = @blah
octave:2> f()
error: blah: no longer valid function handle
octave:2> cd ..
octave:3> f()
executing blah
ans =  5

The message is incorrect because @blah was not a valid function handle at the
time it was created.  It wasn't the case that it was valid, and then became

I think it would be enough to just say "blah: invalid function handle".
