Yes. This should be addressed by patch 9.1.0398. If you see any
additional problems
in using different types of imported variables in a Vim9 script (after

open an issue. In particular, look for any issues in using nested types.

A class in a Vim9 script is a script-local variable. So it cannot be
directly accessed
from outside the script (without using the script name).
