      Description

      If an expression is independent of the scope it is used, (e.g., a getresult, or some other expression) then it should be possible to also percolate that through the expression tree.

      Similar - if a temp table has all values of a particular field having the same value then it should percolate that - possibly on an option.

      cmanden3.eclxml would should significant improvements if this was done, and implicit project was implemented on inline child dataset operations.
