   Amusingly when I ran with the fixed benchmarks the result is basically the 
same (15% slower)
   
   ```
   sqlparser-rs parsing benchmark/sqlparser::select
                           time:   [6.5723 µs 6.5856 µs 6.6010 µs]
                           change: [+14.669% +15.020% +15.364%] (p = 0.00 < 
0.05)
                           Performance has regressed.
   Found 12 outliers among 100 measurements (12.00%)
     11 (11.00%) high mild
     1 (1.00%) high severe
