(PR#1715) Re: package `methods' has persistent effects even if detached

Prof Brian D Ripley writes:

Sorry, forgot to say this is in R-devel (2002-06-27) but not in 1.5.1.

class

.Primitive("class")

find("class")

[1] "package:base"

library(methods)
class

.Primitive("dataClass")

find("class")

[1] "package:methods" "package:base"

get("class", "package:base")

.Primitive("dataClass")

detach("package:methods")
class

.Primitive("dataClass")

so attaching methods is altering the class object *in base*.
Related to namespaces?

A problem in library(), maybe?

All I see is

R/class.R:class <- dataClass

but surely assignments should be in methods and not in base?
