> 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.
