Any idea why S4 doesn't allow slots of type "double"?

> setClass("A", representation(a="double"))
  Error in makePrototypeFromClassDef(properties, ClassDef, immediate, where) :     in making the prototype for class "A" elements of the prototype failed to match the corresponding slot class: a (class “double” )

"numeric", "integer", "character", "complex", "raw", etc... they all work but "double" doesn't. Any reason for this strange exception?
