Reading your messages leaves me a feeling that I'm dumb and this is
something outstanding, or that this is some complex way to print
1, 2, 3, 4, 5.
you're not dumb.  it's _very_ rare that code in itself, without any
hint of its purpose, can be an effective way of communication.

It's an (attempt at an) "with" block/statement/construct using for loops. If you'd just read the "for x in with( do", emphasis on the "with"...

(Code is a language like any other, and can be read like any other. I find this an useful skill to have, as it helps with reverse engineering and tracking down bugs, and it also helps with reading my and other ppl's posts.)
