I recall hitting something like this with the substr/substring function. One
would think they would be identical however they were not (since rust doesn't
do variadic functions nor does it allow defaults for args ala scala or Kotlin).
For the substr it was expanded to two functions that internally used a vec<>
and handled the logic of using the optional 3rd argument there.
```
#[doc = "substring from the `position` to the end"]
pub fn substr(string: Expr, position: Expr) -> Expr {
super::substr().call(vec![string, position])
}
#[doc = "substring from the `position` with `length` characters"]
pub fn substring(string: Expr, position: Expr, length: Expr) -> Expr {
super::substr().call(vec![string, position, length])
}
```
