alamb opened a new issue, #10397:
URL: https://github.com/apache/datafusion/issues/10397
I think it is possible to take `Vec` like what functions-array
macro does
```rust
($UDF:ty, $EXPR_FN:ident, $DOC:expr , $SCALAR_UDF_FN:ident) => {
paste::paste! {
// "fluent expr_fn" style function
#[doc = $DOC]
pub fn $EXPR_FN(arg: Vec<Expr>) -> Expr {
Expr::ScalarFunction(ScalarFunction::new_udf(
$SCALAR_UDF_FN(),
arg,
))
}
```
