> Provide a more intuitive way to construct nested dataset:
> ```python
> # instead of using confusing factory function
> dataset([
>      factory("s3://old-taxi-data", format="parquet"),
>      factory("local/path/to/new/data", format="csv")
> ])
> # let the user to construct a new dataset directly from dataset objects
> dataset([ 
>     dataset("s3://old-taxi-data", format="parquet"),
>     dataset("local/path/to/new/data", format="csv")
> ])
> ```
> In the future we might want to introduce a new Dataset class which wraps functionality of both the dataset actory and the materialized dataset enabling optimizations over rediscovery of already materialized datasets.
