# Description 1. Make table to be a subtype of `list<any>`, so some input_output_types of filter commands are unnecessary 2. Change some commands which accept an input type, but generates different output types. In this case, delete duplicate entry, and change relative output type to `<any>` Yeah it makes some commands more permissive, but I think it's better to run into strange issue that why my script runs to failed during parse time. Fixes #11193 # User-Facing Changes NaN # Tests + Formatting NaN # After Submitting NaN
