There were several misunderstandings:

I used "" to quote it in the english text, not for rc. I maybe should 
have pointed that out.

Sure. Four. I should learn counting again...

Note that I was talking about the 'visual' appearance, like, what you get 
when echoing the list/variable or 'what you see on the screen'. When you 
see the string "this is a string" (without the '"') on the screen inside 
your window as an output there's no way to know how long the list is.

I guess even when capturing the output with `{...} it is still impossible 
to know that, because then rc is reevaluating the string into a list.
