     ifconfig [-L] [-k] [-m] [-n] interface [create] address_family [address
              [dest_address]] [parameters]
...


     The following parameters may be set with ifconfig:
...
     -alias  Remove the network address specified.  This would be used if you
             incorrectly specified an alias, or it was no longer needed.  If
             you have incorrectly set an NS address having the side effect of
             specifying the host portion, removing all NS addresses will allow
             you to respecify the host portion.
...
     delete  Another name for the -alias parameter.


Parameters go last as clearly stated in the beginning of the man page and
that works well:

root at lion3:/home/test # ifconfig lo0 inet6 2001:db8:ffff::ffff/128 alias
root at lion3:/home/test # ifconfig lo0 inet6 2001:db8:ffff::ffff/128 delete
root at lion3:/home/test # 


The fact that for inet you could give it in the beginning and other minor
things leniently allowed have caused a lot of trouble the last years.
We try to stay more strict even if there's no real grammar, even if it
wasn't for SVN.
