expression sequence, or Vector

restart:
f := (x,y) -> x*y+x^2+1:  # this expects two arguments
g := t -> (2*t, 3*t):     # this returns an expression sequence

(f@g)(x);
                               2    
                           10 x  + 1

unapply( (f@g)(x), x );

                                 2    
                        x -> 10 x  + 1


restart:
f := (V::Vector) -> V[1]*V[2]+V[1]^2+1:   # this expects a Vector
g := t -> <2*t, 3*t>:                     # this returns a Vector

(f@g)(x);
                               2    
                           10 x  + 1

unapply( (f@g)(x), x );

                                2    
                       x -> 10 x  + 1

Thanks. For my purposes I prefer the first version.
