Also in `ScalarUDFImpl` trait:
```rust
/// Returns true if some of this `exprs` subexpressions may not be
evaluated
/// and thus any side effects (like divide by zero) may not be
encountered
/// Setting this to true prevents certain optimizations such as common
subexpression elimination
fn short_circuits(&self) -> bool {
false
}
```
