Varför kan jag inte inte anropa A -- B -- C ?

[Lennart Öhman]

Hi, the -- operator works with two arguments. I think you shall
concider what you did as:

[1,2,3,4,5,6] -- (A -- (B -- C)).

If you try

((([1,2,3,4,5,6] -- A) -- B) -- C).

I beleive you will accomplish what you intended.

Best Regards,
Lennart
