I think I've seen this trick on the mailing list before.

Create a file called funcs that contains (you have to use endfunction):

xcsdfg = 1;
clear xcsdfg

function y = sum2(x)
y = sum(x);
endfunction

function y = prod2(x)
y = prod(x);
endfunction

Then in Octave:

$ octave
Octave 2.9.3 Forge 20050613
>> sum2([1 1])
error: `sum2' undefined near line 1 column 1
>> funcs
>> sum2([1 1])
ans = 2
>> prod2([1 1])
ans = 1
