No one is talking about getting *rid* of loops. But often it is clearer and more efficient to express operations as sets, or as combinations of filters on a sequence.
I'm not sure what sort of insecurity you describe with message-passing. Are you using the phrase in the sense in which Smalltalk and Ruby use it?

Use whatever HTTPS-terminating server you want, really. You can hook flask into Apache if you want to be 90s about it, or you can run a (say) gunicorn server on localhost to run your appservers and proxy it through whatever front-end Web server you prefer.

You have to be careful, because Flask did start out as a joke. The author of a WSGI library was laughing at the "one-file Web framework" trend of 2007 or so, and released Werkzeug bundled with Jinja and some glue code as a single file. It turned out to be incredibly useful!

Exactly. And Flask has a wide body of library code for you to assemble in the way you need.
The Rails motto of "code, not configuration" is an enticing one, for this. Instead of giving you a giant Microsoft Office-type all-singing-all-dancing Application to Configure, you get individual libraries of code you can include and plug together.
The actual downside to this is that you get a network effect as the possible interactions between pieces multiplies. This isn't completely avoided in a monolithic application, however, and many "unsupported configuration" situations would be problematic module interactions in another architecture.
