[Octave-bug-tracker] [bug #51586] Creating method handle fails using str2func

[Piotr Held]

Follow-up Comment #7, bug #51586 (project octave):

Thanks for taking your time to look at my ideas and the few lines of code I
wrote!

For my needs the approach you suggested (that is closing this bug) is
sufficient. However, I believe that in that case the error message needs to be
changed. 

With this class:
 
classdef creating_method_handle < handle
  methods
    function foo (self)
      1;
    end
    function tst1 (self)
      f = @foo; % or str2func('foo') or str2func('@foo')
      f(self);
    end  
  end
end


When calling 

a = creating_method_handle;
a.tst1();


The response from the interpreter is:

@foo: no function and no method found


This behavior suggests that it should be possible to create a method handle.
If it is undesirable to create a method handle *anywhere* then the error
message should be changed as well.

Because of this error message and the fact that someone had implemented
parsing for creating a method handle within
libinterp/octave-value/ov-fcn-handle.cc:make_fcn_handle() I will bring it up
on the mailing list.
