Infinite loop when trying to write a for-loop

[jglick]

for (int i = 0; i < array.length; i++) {…}

works (with or without the sandbox) but

for (i = 0; i < array.length; i++) {…}

loops endlessly in the sandbox, with i always 0.

The problem here is that i++ for local variable i is handled correctly, but i++ for property i isn't.

The underlying issue I'm uncovering is that the semantics of postfix operator i++ cannot be properly preserved with local transformation of an expression.

Given a++, I need to basically do something like {b=a,a=a.next(),b} so that the whole expression evaluates to the value prior to increment, but how do I do that!?

By using literal list support, I think [a,a=a.next()][0] would do
