> Since we have the option to either emit an `NA` or error on parsing fail,
could we capture this behavior?
We could, but _if_ we use `coalesce()` (not saying we should, but it's the
best I was able to come up with), then we'd need to build the iteration
something like:
```r
coalesce(
build_expr("strptime", ..., error_is_null = TRUE)
...
build_expr("strptime", ..., error_is_null = FALSE)
)
```
Because we'd still try the various formats and we want to error or return NA
only if all of them fail to parse.
