[Cook] Function Arguments (and Algebra)

[Pendergraft, Jerry]

Essentially you can pass lists by name (think reference) rather than content.
foo = one two three;
bar = a b c;

1) [myfunc foo bar];
vs:
2) [myfunc [foo] [bar]];

In 1 you would write myfunc to expand the lists ala:
  dosomething with [@1];
  somethingelse with [@2];

in 2) you get content of both lists concatenated.
Sounds like you want to use #1
