Well, what about an abstraction?

To mimic Max/Cyclone [prepend] as in "list a b c" ==> [prepend set]
==> "set a b c" you need to use [list trim] afterwards. 

However to convert "a b c" to "list set a b c" you only need one [list
prepend set], whereas to get a "list"-list out of Max-[prepend]
requires a conversion using a second object (like [list]). 

See attached patch for an example. Either way you look at it: In one
case, you always need two objects, unless list-semantics totally
change.

Ciao
