function handles & closures - porting from matlab

[Ian Rickard]

I'm currently trying to port a code base from matlab to octave.  It
uses the following pattern extensively:

function fns = gen_poly_funs(n)
    fns = arrayfun(@(n)(@(x)x.^n),0:n,'UniformOutput',false);
end

As far as I can tell this pattern breaks in Octave, as there appears
to be a single global value for n.  Is there an easy way to mimic
matlab's behavior where the n is unique for each of the returned
function handles?
