I have a function that takes arguments:

function top (Page p, Entry[] e, Comment[] cs)

And I would like to not have the argument for Entry[] if the function is called from EntryPage, and not to have Comment[] if it's called from Recent/Friends. Is it possible? I tried this, but am getting an error message ("Expected identifier"):

function RecentPage::lay_spammertop() {
top($this, $this.entries, null []Comment);
}

function EntryPage::lay_spammertop() {
top($this, null []Entry, $this.comments);
}

Thanks!
