Looks like function names like "abs" or "substring" are treated as reserved keywords, so for instance you can't have a path called substring. This is needlessly restrictive. We should have a very minimal set of keywords (e.g. "and", "or", "not"). Functions can be easily distinguished from paths by the presense of parenthesis.
