From the thread "Special variables"
I am uncertain if functions can be written exactly as modules with the
ability to return a value unrelated to any passed parameter or any special
variable. I am finding out that I do not understand how to "return" an
arbitrary value.
User defined functions can return just about anything
var=" regular variable ";
$v =" special variable ";
function junk(input=13) = ["this is a test function which returns
",var,$v,[input],[1,2,3,4],[2:6]];
echo(junk());
ECHO: ["this is a test function which returns ", " regular variable ", "
special variable ", [13], [1, 2, 3, 4], [2 : 1 : 6]]
