in old patches you have
$1 $2 $3 in messages
and $0 $1 $2 in objects
presumtion: you don't just simply want to add $0-feature to messages 
simply because it would be inconsequent, or difficult to understand for 
newbies...
therefor you want to differentiate between creation and message 
arguments. giving one of them a new appearance, but still making old 
patches work.
case 1 (bad):
you have
$0 $1 #1 $2 #2 $3 #3 in messages
and $0 $1 $2 $3 in objects.
(that's bad because, then u still have the confusion of $0 and $- in 
messages, exactly what you did not want
case 2 (better):
you have
#0 #1 #2 #3 #4 $1 $2 $3 $4 in messages (all meaning different things)
and $0 or #0, $1 or #1, $2 or #2 in objects. (#- the new style, but for 
backwards compatibilty still allowing the old $- style)
hope this is clear enough.
marius.
