      Description

      When using the RDataFrame::Alias function to define a new variable X on a node, subsequent attempts to use the same variable name X on other sub-nodes result can lead to unexpected values of X on the second subnode.  An example implementation to reproduce the surprising behavior is available in this gist. In this implementation, no matter what definition of "newVar" I use on the second subnode, I always get back the values from the first subnode.
