R devel - Sep 2003 - another dump/source problem?

Is this a bug?

I do this:

    library(mva)
    data(USArrests)
    d <- dist(USArrests)
    dump("d", "tst")
    q()

I restart R and do this:

    source("tst")

And I get:

    Error in as.matrix(x) : Object "USArrests" not found

 system = i686, linux-gnu

Yes.  If you look inside the saved file it contains

	..., call = dist(x = USArrests), ...

When this is reread, an attempt is made to evaluate the call.
Some kind of quoting is needed.
