As seen in Dave Kane's question and my response, one needs the "character.only"
argument to library() in order to make a loop like this work:
R> for (i in rlibs) library(i, character.only=TRUE)

It seems like a similar option would be useful for detach():
R> for (i in rlibs) detach(paste("package",i,sep=":"))  # FAILS!
and any other functions which immediately run substitute() on their arguments.
