I understand your concerns with *args and **kwargs. I think we need to
find a solution for that eventually.
One other thing about InitVar: it lets you control where the init-only
parameter goes in the __init__ call. This is especially important with
default values:
This is indeed a nice property. I was thinking about that myself and how
to best handle it. One use case that could occur in out codebase is
passing in a "context" argument. By convention, this is always the first
argument to the constructor, so it would be nice if this would also work
for dataclasses.
