Member predicate Call::Call::getAnArgumentSubExpr

Gets a sub expression of the argument at position index. If the argument itself contains calls, such calls will be considered leafs in the expression tree.

Example: the call f(2, 3 + 4, g(4 + 5)) has sub expression(s) 2 at index 0; 3, 4, and 3 + 4 at index 1; and g(4 + 5) at index 2, respectively.
