What do you think about this idea ?

This could already be handled with the seq and mat2list commands
F2(X) : X^{2*mat2list(seq(K,K,1,2,0.5))}

It's too bad seq() doesn't just return a list instead of a vector.

Quote:F4(X) : [1,2]*X^2+[2,3]*X => 4 curves (1,2); (1,3); (2,2); (2,3)

This could get quickly out of hand.
F4(X) : [1,5]*X^2+[1,5]*X+[1,5]
would generate 125 curves. Typically, a user would want few enough curves to just use the other syntax.
F4(X) : {1,1,2,2}*X^2+{2,3,2,3}*X => 4 curves (1,2); (1,3); (2,2); (2,3)
