>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 3.4.0

> For try_cast and the legacy cast (cast with ANSI SQL mode off), there are conversion which has the same behaviors:
>  * cast(string as date/timestamp/TimestampNTZ)
>  * cast(string as double/float/decimal)
> So, the try_cast can be faster if it uses the evaluation code path of the legacy cast, instead of turning into ANSI cast and catching exceptions.
