[Rd] standardization of slot access

I'm usually confused about when to use 'slot' or '@'. I've frequently read that it's always preferable to use accessor functions, so I would think the '@' operator should be avoided. However, ?slot contains the following advise:

"Generally, the only reason to use the functional form rather than the simpler operator is _because_ the slot name has to be computed."

How do we decide whether to use the function or the operator?
