yeah I do, for that I wrote "personal". ;)
I like it regarding "readable code" for others.
It became a way more important parameter in my coding style as I dealt with different coding styles in the same appian element and got in trouble to understand the different approaches/fixes of the same issue within a few code lines.

As you know, using foreach to filter lists is not my prefered way.

Best way I have ever seen, stefan

my personal method:

a!forEach(
    items: enumerate(100)+1,
    expression:{
        if(
         mod(fv!item,2),
         {},
         fv!item
        )
    }
)

requirements:
if needed, check the mathematical meaning of modulus and how its working.
the value 1 (as integer) -> can be interpreted as the boolean value "true"
and the value 0 as false.

reject( /* Drops number where fn!mod returns 1 */
  fn!mod(_,2), /* Returns 0 for even numbers */
  1 + enumerate(100) /* Create list 1 ... 100 */
)
