[Grace-core] 0..(size-1) or 1..size

Well I'd like that - let's see what Kim says when he gets back.

***no! more gratuitous complexity...***

right: so I really should write 

for (coll.bounds) do { i -> blah }

or we could do

for (coll) doWithIndex { e : Element, i : Number -> ... }
sending  along an extra argument that's a Number

(or support this with for/do if we can pass extra arguments to a block)

argh! we must sort out matching & typesystem & modules;
then get on to the libraries
