OpenBSD PF set skip on rule not working

[fbsd_user]

I have this rule in my PF rules file. When I load the rules I get syntax
error on the rule.
set skip on lo0             # No restrictions on Loopback Interface

The OpenBSD PF manual says this is good syntax.

Does any FreeBSD PF users use this and does it work???


Also is there some command to display the bad syntax line along with the
error message?
