"C" appears to be an illegal name for a slot in an S4 class (example below). If this is a known limitation, and not a bug, it would be nice if it were caught by setClass.

Error in methodsPackageMetaName("C", name) :

        'The name of the object (e.g,. a class or generic function) to find in the meta-data' must be a single string (got an object of class "numeric")

> setClass("testobj", representation ( C. = "numeric"))
[1] "testobj"
> new("testobj", C.= 2)

An object of class "testobj"
Slot "C.":
[1] 2
