## Transmute

This function is equivalent doing a `mutate`, followed by a `select` to keep the recently defined columns. Currently the way it works is...

* Positional arguments are used to select columns
* Named arguments are used as in mutate

```{python}
from siuba import _, transmute
from siuba.data import mtcars
```

```{python}
mtcars >> transmute(_.cyl, _.mpg, hp_per_cyl = _.hp / _.cyl)
```
