The only advantages slices have left
are (a) type syntax, i.e. T[] instead of Slice!T, (b) literal syntax,
i.e. [ 1, 2, 3 ] instead of slice(1, 2, 3), and (c) a couple of stray
language bugs such as '$'.
I am thankful for $, as it is a great feature, and it really should be
made accessible to user defined types. Either through opDollar or the
rewrite a[foo($)] => a[foo(a.length)]. What makes it qualify as a stray
language bug to you?
He's saying that one of the few advantages slices have left over
user-defined types is that, for slices, $ actually works. The bug is
that it
doesn't work for user-defined types.
FWIW, I like the rewrite idea far better than opDollar.
opDollar is more powerful because it can be made to work with infinite
ranges.

What would it return?
