Class ExpandSpecial

java.lang.Object
  org.eclipse.internal.xtend.expression.debug.BaseSpecialTreatment
      org.eclipse.internal.xpand2.debug.ExpandSpecial

public class ExpandSpecial
extends BaseSpecialTreatment

An ExpandStatement calls monitor.preTask() always twice in case of isForeach. The first call is for the Statement itself and the second for every execution of the included definition.
We remember each call on a Stack and use the first entry to store count and number of loops.
This (outer) frame is hiddened.

We do this whole mechanism (different from the Java behavior) that the user can go over one execution of the EXPAND with Step_Over and go over all loops with Step_Return. In Java this behavior is not possible. There is the Ctrl+R functionality, what is not implemented for our debug model.

We can't use an empty iterator as in Foreach, because an expand could be called iteratively.
Therefore we remember each 2nd time the statement together with it's target element count.
