The undocumented trick to turn a range into a vector never needed the usage of the vectorization operator!
As @DJNewman already wrote this undocumented feature was removed with version 10 of Prime, unfortunately without providing a "legal" alternative.
So by now you either have to use your own user defined function to create the necessary vector right ahead, or you use a function which turns an existing range into a vector. You can find some suggestions in the thread @DJNewman linked to.
For example:

You could use this very same function also to create the vector right ahead using a local assignment

but you can't type it in that way because Prime won't allow you to provide the second, comma separated value of the range (0.35). You would have to type it in an empty place on the sheet and then use copy and paste. Awkward, so you may be better off with one of the other functions if you want to create a vector without the detour via a range variable.
