If you're storing the value for later use: (Additional values in the vararg are ignored)
If you're running it through a function and just want the first value to be passed: (Parenthesis trim the value list to only allow the first to pass through)
The reason
select(1,...) does nothing is because it's an arg shift function, you're telling it to shift the args so it starts at index 1, which it at the beginning of the vararg list.
