As I said we can use other characters, I am warming to the ; proposal.

I am happy with @ for slices and $ for single elements assuming the deref
stuff can be resolved.

I am anxious to avoid too many levels of brackets as they just look plain
ugly. 

$a[$i;$j;$k] for a single element would do it for me, and @[10..20;10..20]
for a slice.

I don't believe we should bend over backwards not to break any existing perl5
syntax, that was done for perl4->perl5 and had led to all kinds of uglyness.
