[GitHub] [arrow-datafusion] andygrove commented on pull request #3841: Tweak list of optimization rules

   I've just started reviewing this PR and noticed one difference in one of the queries I tested with that might not be optimal.
    
   ## before
   
   Table scan filter: `CAST(col1 AS Int64) BETWEEN Int64(4) AND Int64(4) + Int64(3)`
   
   ## after
   
   Table scan filter: `CAST(col1 AS Int64) >= Int64(4), CAST(col1 AS Int64) <= Int64(7)`
   
   It looks like we are now performing the CAST twice.
