1, I have to use a non-trivial library or "module" for a simple task, and I
don't want to write 20 line of code, and introduce 4 helper variable.
2. I want to get from point 1 to point 5 but I'm not interested in the steps
in-between (classical method chaining), but sadly one of the steps requires
object instantiation.
