Patch 8.2.1042
Problem: Vim9: cannot put an operator on the next line.
Solution: Require a colon before a range to see if that causes problems.

! To make it possible for the operator at the start of the line to be
! recognized, it is required to put a colon before a range. This will adde
! "start" and print: >
! let result = start
! + print
! This will assign "start" and print a line: >
! let result = start
! :+ print
