   > [..] We can keep that for a separate PR.
   
   different pr sounds good.
   
   we should also start split different optimizations to different files to 
make it more manageable.
   
   also, we need to add a way to check if expression can fail or not (e.g. 
divide can fail on divide by 0), column cannot fail (unless of course the 
column is missing)
   
   this way it open another optimization for this that we can evaluate both in 
case it is cheap and do simple zip.
   
   but for now we can add another optimization for column/literal or 
column/literal and do a simple `zip`
