Ever wondered which R functions are actually passed to internal C code? Well, wonder no more as it turns out there is an unexported named list within the `methods`

package providing instructions for turning builtin and special functions into generic functions. Wrapping this list with `names()`

gives us the list of all R functions which wrap calls to `.Primitive()`

.
