Some of them have been resolved and a few others are among the patches listed above. However, I know for sure that there are still issues with typeset. In particular with -p and -m when applied to named references.

-m is not supposed to work at all with named references.

I disagree (except in ksh emulation mode).  There are other parameter
cases where ksh has errors but zsh has traditionally yielded empty
string.

However, I agree that anything other than behaving like
${an_unset_scalar} would be dubious.
