>             Project: Pig
>          Issue Type: Improvement
>          Components: impl
>    Affects Versions: 0.3.0
>            Reporter: Santhosh Srinivasan
>
> The graph operations swap, insertBetween, pushBefore, etc. have to be 
> re-implemented in a layered fashion. The layering will facilitate the re-use 
> of operations. In addition, use of operator.rewire in the aforementioned 
> operations requires transaction like ability due to various pre-conditions. 
> Often, the result of one of the operations leaves the graph in an 
> inconsistent state for the rewire operation. Clear layering and assignment of 
> the ability to rewire will remove these inconsistencies. For now, use of 
> rewire has resulted in a slightly less maintainable code along with the 
> necessity to use rewire with discretion.
