If I understood correctly STREAM is the most simple approach because it works on a pair of elements in input, then comes DOLIST that is a bit more generic and then DOSUBS (that allows the usage of NSUB/ENDSUB).

Am I mistaken?

You could also add ΣLIST, ΔLIST, and ΠLIST to your, um, list.

And you may want to start your exploration by considering even simpler constructs, such as:

Code:

{ 1 2 3 }
3
*

or

Code:

{ a b c }
{ 1 2 3 }
/

...since many simple functions also do something meaningful when given one or more lists as parameters.
