Review Comment:
   Your PR description is beautiful -- I thin some part if it would be valuable 
to include in the comments as well for future readers:
   
   ```suggestion
               // Support expressions like `interval '1 month' + 
date/timestamp`. 
               // Such expressions are parsed like this by sqlparser-rs 
               // 
               // Interval
               // BinaryOp
               //   Value(StringLiteral)
               //   Cast
               //     Value(StringLiteral)
               // 
               // This code rewrites them to the following:
               //
               // BinaryOp
               //   Interval
               //     Value(StringLiteral)
               //   Cast
               //      Value(StringLiteral)
               SQLExpr::BinaryOp { left, op, right } => {
   ```
