This implementation made me think of the various as.* methods we have defined [1] (since this is similar to as.Date()). Which all use a simpler setup to create a cast operation. However, I noticed that for those, they are using Expression$create(...) rather than the build_expr(...) helper [2]. That build_expr(...) here should handle the wrapping of R objects into Scalars (...)

(...)We should also open a jira if one doesn't exist to clean up those as.* methods to use build_expr()
