Is this a bug?  Certainly it was not expected.  dump() seems to prefer a
global definition over a local one.  R 1.6.1 on Solaris 8 or NetBSD:

> ls()
> dump("D", "D.q")	# a global D() exists
> system("cat D.q")
"D" <-
function (expr, name)
.Internal(D(expr, name))
> D <- function(x) print(x)	# now create a local one
> ls()
[1] "D"
> dump("D", "D.q")
> system("cat D.q")	# here's the surprise
"D" <-
function (expr, name)
.Internal(D(expr, name))
The same thing happens with dump(list=ls(), "D.q").
