[list split 1]

[list prepend]

Above examples *do* work with any message. 

Not that *you* need to decide what you want to get afterwards:
list-messages or meta-messages.  Search the archive for the
differences between both. You can convert any list-message that starts
with a symbol to a meta-message with [list trim]
