    Description

      Related to HPCC-28348.

      Sometimes because of the way nested attributes are defined it is possible that ECL simplifies to

       

      IF(cond, PROJECT(IF(cond, x, y), z); 

      This is much better evaluated as

      IF(cond, PROJECT(x), z);

      This can be optimized as the code is being generated.
