to make the point differently, i'd expect the following two to be
equivalent:

    x = c(1); 'names<-'(x, 'foo'); names(x)
    # "foo"

    x = c(1); do.call('names<-', list(x, 'foo')); names(x)
    # NULL

but they're obviously not.  and of course, just that i'd expect it is
not a strong argument.
