> It would be nice for development and testing to be able to build linear DAG dependencies with unary + operator rather than with << with automated upstream dependency to the previously added task.
> Often during development we need to inject/remove tasks between two other tasks and with unary operator it might be very easy to comment out whole lines of code.
> Example:
> {code:java}
>  +op1
>  +op2
>  +op3{code}
> might be equivalent to:
> {code:java}
> op1 >> op2 >> op3{code}
> This way we can comment out one line:
> {code:java}
>  +op1
>  # +op2
>  +op3{code}
>  equivalent to:
> {code:java}
> op1 >> op3{code}
>
