About Slot-Value

• You can always access a slot using slot-value

• The general rule is to prefer accessor methods (e.g. x-position and y-position) over raw slot-value.

• Exceptions:

  • When the accessor function has a lot of :after, :before, or :around methods, slot-value is faster
  • The accessor function may have :after methods that you want to avoid in some cases
