Element as @ parameter (was Re: Cubist's first bug report)

I tried to make LiveCode crash fiddling with side-effects using this.  So far, I have not been able to.  As most of us have come to realize; there are some very smart people in Scotland.  

This is a very handy feature.  I usually use a functional style (using lots of simple, pure functions) but sometimes I want to maintain mutable data.  This is very handy.  I can have an array of queues!  

I am a little embarrassed that I didn't notice when this came out.

A side-effect of this was that we were able to implement the ability for array elements to be able to passed by-ref (to @ parameters) which they previously could not.
