You don't need to serialize the list for this: a message box has a
"set" method, as you know. You can construct a list starting with
"set" by prepending "set" in front of any list using [list prepend
set]. Now as (almost) all [list] objects generate proper list
messages, whose first word, the selector, always is "list" unless the
list-message starts with a number, you need to strip this
"list"-selector first. For that, [list trim] was made. It will make
something like "list set a b c d ..." into just "set a b c d ...". Put
all this together and you get this:

 "anything and more"

 [list prepend set]
