I know, I was not talking about that, but about the original problem of
dynamically generating messages. Sorry if that was not obvious.

Let me explain:
In order to convert lists to messages I normally use message boxes with
$ arguments. E.g if I send a list "foo 2" to  [set $1 $2( it will
construct a message that reads [set foo 2(,
similar with a 3 element list and $1,$2,$3.
Now, my proposal is to introduce a $@ dollar symbol which accepts
lists of any length, this way it is not necessary to know the
length of a list before converting it into a message.
Hope this makes it clearer.

Cheers,
Guenter
