Review Comment:
Looks great so far. Could you add tests with a regular R object? Something
like:
```r
compare_dplyr_binding(
.input %>%
mutate(y = qday(as.Date("2022-06-28")) %>%
collect(),
test_df
)
```
I think this would fail, but there's an easy solution: replace the
`Expression$create()` call with a call to `build_expr()` (which automatically
converts an R object into a scalar).
