I can't figure out how to dynamically take a portion at a time of a column vector in Maxima; for example I have the vector v = [a, b, c, d, e] and I want to take this: [a], [a, b], [a, b, c], etc. How can you do this in Maxima?

Ran in:
v = [1 2 3 4 5] ;
N = length(v) ;
iwant = cell(N,1) ;
for i = 1:N
iwant{i} = v(1:i) ;
end
celldisp(iwant)
iwant{1} = 1 iwant{2} = 1 2 iwant{3} = 1 2 3 iwant{4} = 1 2 3 4 iwant{5} = 1 2 3 4 5
