@felixcheung Thanks for your comments. I changed ```stopifnot```. At L3925
I could add
```
hintList <- list("hint2", "hint3", "hint4")
hint(df, "hint1", 1.2345, hintList)
```
but I am a little hesitated to give an example. Even though we relax the
check for hint, I am not sure how the numeric hint or list hint is used in real
sql.
