I find this bizarre. I am absolutely certain that I want to view $f$ as a polynomial in one variable and evaluate it at 10. I can think of lots of alternate ideas (evaluate everything to bottom!) but I believe none of them are common. Can you cite a paper that uses the notion of $x^3$ denoting the three-fold composition of a function $x$ and considering $f = x^3$ and $f(10)$ intending the three- fold composition of $x$?
