Maybe you are looking for

eval(expr, [kernel=replacement])

or

eval(expr, operator, arglist +-> transformation(arglist))

eg:

(1) -> f := operator 'f

   (1)  f
                                                          Type: BasicOperator
(2) -> eval(x*f(x), [f(x)=g])

   (2)  g x
                                                     Type: Expression Integer
(3) -> eval(x*f(x), f, l +-> z)

   (3)  x z
                                                     Type: Expression Integer

(note that in the results blanks denote multiplication, not application...)
