Review Comment:
> `TypeSignature::Coercible` is designed to cast between the same logical
type, but now it casts to any kind of type, I don't think this is ideal.
This is what the doc comments say:
```
/// One or more arguments belonging to the [`TypeSignatureClass`], in order.
///
/// For example, `Coercible(vec![logical_float64()])` accepts
/// arguments like `vec![Int32]` or `vec![Float32]`
/// since i32 and f32 can be cast to f64
///
/// For functions that take no arguments (e.g. `random()`) see
[`TypeSignature::Nullary`].
Coercible(Vec<TypeSignatureClass>),
```
