Hi all, 

When I am differentiate the composite functions, I wanna make the output more elegant.

For example, from the following code:

A__1 := A__0 + k(e)*a__1;
diff(phi(A__1), a__1);

I define a function phi(A__1) and function A__1(a__1), and the latter is known. 

But Maple output:

D(numtheory:-phi)(A__0 + k(e)*a__1)*k(e)

I think "D(numtheory:-phi)(A__0 + k(e)*a__1)" part can be simplified into d(phi)/d(A__1).

Do you have some ideas? Thanks!
