<lang parigp>compose(f,g)={
x -> f(g(x))
};
fcf()={
my(A,B); A=[x->sin(x), x->cos(x), x->x^2]; B=[x->asin(x), x->acos(x), x->sqrt(x)]; for(i=1,#A, print(compose(A[i],B[i])(.5)) )
};</lang> Usage note: In Pari/GP 2.4.3 the vectors can be written as <lang parigp> A=[sin, cos, x->x^2];
B=[asin, acos, x->sqrt(x)];</lang>
