If you would like to do this with a more common type of
expression and hide the details, you can define
\begin{axiom}
op(n,x) == interpret((x::InputForm).(n+1))

The domain InputForm can be quite useful for manipulating parts
of expressions. For example

Hi,

It can be done in maple via the indets() command. I think the
equivalent in MMA is Variables[].
If you have an expression as a tree, one just needs to traverse it and
examine symbols therein.
