Implement yield using a state machine

[GoogleCodeExporter]

Create an infinite sequence:

public static IEnumerable infinite()
{
  while (true)
    yield return 1;
}

The generated code will not terminate:

function infinite()
{
    var $yield = [];
    while (true)
    $yield.push(1);
    return $yield;
};

For the implementation details have a look at:

Thanks, I'd love to add this feature, although it's a bit more tricky, since 
JavaScript does not have a 'goto' keyword, so the .NET implementation can't be 
used as/is. It has to be modified and adapted. The code you currently see is a 
simpler, pre-processed implementation, in which if you use yield, it will 
process the items immediatly (and not lazy), and return a list with the results.
