That's also possible, however, the docs say that "subs" should substitute an expression, not just a variable, thats why I've tried the substitution above. It does, and it does it's best to use heuristics to find that expression, but it can only go so far, and if the expression itself is not there, it can fail. Substituting a Symbol will always work.
