Review comment:
The `tryCatch(...)` now looks like this and I think it's a step in the
right direction:
```
tryCatch(
vec_to_Array(x, type),
error = function(cnd) {
attempt <- try(vec_to_Array(x, NULL)$cast(type), silent = TRUE)
if (!inherits(attempt, "try-error")) {
message("Hint: You might want to try casting manually. Something
like `Array$create(...)$cast(...)`")
}
stop(conditionMessage(cnd), call. = FALSE)
}
)
```
