Follow-up Comment #19, bug #39257 (project octave):

What value of variables from the enclosing scope is supposed to be used?  The
value at the time the handle is created?  What about something like this

function [fh1, fh2, fh3] = foo (y)
  fh1 = @nest;
  function r = nest (x)
    r = [x,y,z];
  z = 3;
  fh2 = @nest;
  z = 4;
  fh3 = @nest;

Given the above function, what does Matlab do for

[fh1, fh2, fh3] = foo (2);
fh1 (1)
fh2 (1)
fh3 (1)
foo (20)
fh1 (1)
fh2 (1)
fh3 (1)


In any case, I suspect that this is too complicated to fix properly for 4.4
and will have to wait until later, so I will likely undo the change I made
earlier today.
