> In the docs for {{schema()}}, the ellipses argument is documented as "named list of data types".
> However, if I create a schema using a named list, e.g.
>  
> {code:java}
> share_schema <- schema(
>   list(
>     company = utf8(),
>     price = float64(),
>     date = date32()
>   )
> )
> {code}
> I get the error: \{{Error: !is.null(nms <- names(.list)) is not TRUE }}
> We should:
>  # Rephrase the documentation of that argument so it doesn't say to use a named list
>  # Update the error message shown if a named list is supplied to be a little clearer about what the user has done wrong
>
