Support for empty initialization for loop

[GoogleCodeExporter]

It's sometimes useful to not initialize a variable in for loops. As a 
simplified example:

var offset = new Pos();
var queue = new LayoutQueue();

var poly = queue.Start();
for (; queue.HasMore(); poly = queue.Next())
{
    offset.Translate(poly);
    ....
}

if (poly.IsClosed)
{
    paintPoly(poly);
    ...
}

The SharpKit compiler refuses the for loop with:

"SharpKit.Compiler.CompilerException: Sequence contains no elements ---> 
System.InvalidOperationException: Sequence contains no elements"

I can work around it by putting in a dummy variable but it would be nice to 
have support.
