Thanks for your opinions. I'll take them into account.

Mostly a matter of taste, but also it has a history, using an underscore
for private members has been used in many style guides (even if the
language doesn't do anything with it).

Yes, we should support private methods. The question then is how to
specify that. Using the same mechanism as for members would be
expected. With an underscore:
this._privateMember = 'text'
def _PrivateFunc()
With a keyword:
private this.privateMember = 'text'
private def PrivateFunc()
To me this doesn't appear to change the preference for how to mark
members as private.

No, we should not allow that, it is not only confusing, it also makes it
difficult to change a member from private to public later.

Not sure. "final" is an extra mechanism and it doesn't add
functionality. It is mainly useful in larger, multi-person projects
where you don't want others to overrule your class/method/etc.
It can make writing tests more difficult.
