Aren't you creating new arrays to pass to indexed here? If that's the case, $
isn't associated with any particular array, and I don't see how it could work.
Now, there's issue# 7177
http://d.puremagic.com/issues/show_bug.cgi?id=7177
which aims at getting opDollar to work with ranges which have length (which it
generally doesn't at this point), so that might be related to what you're
looking for, but if what you're looking for is [0, $-1] to work on its own, I
don't see how that could ever work, because $ only works when slicing or
indexing, and [0, $-1] in the context above is an array literal.
