> {code:sql}
> SELECT reflect("java.lang.String", "valueOf", 1),
>        reflect("java.lang.String", "isEmpty"),
>        reflect("java.lang.Math", "max", 2, 3),
>        reflect("java.lang.Math", "min", 2, 3),
>        reflect("java.lang.Math", "round", 2.5),
>        reflect("java.lang.Math", "exp", 1.0),
>        reflect("java.lang.Math", "floor", 1.9)
