Why not just use struct()? Let's say I'm defining a package called moo in 
/tmp/moo:

---8<---
function b = f(a) 
       b = a + 2;
end
                
function b = g(a) 
       b = a + 3;
end
                                
# emulate package being loaded as
# pkg load moo as moo
                              
moo = struct("f", @f, "g", @g);
         
clear f
clear g  
---8<---

Then I can do:

octave:1> source('/tmp/moo')
octave:2> moo.f(4)
ans =  6
octave:3> moo.g(4)
ans =  7
octave:4> f
error: `f' undefined near line 4 column 1

where I am using the "source" command above as a replacement for "pkg load moo as 
moo".
