hi,

i've a question regarding the compose function objects. i was wondering 
if there is something like compose_f_x_gy etc? i know there's only the 
compose_f_gx_hy function object. but then i would need g(x) = x, so my 
question: is there another way to get the same result like using g(x) = 
x or writing a compose_f_x_gx?

thanks, daniel
