Hi,
Thanks to those who provided me examples.
I'm glad everyone else has had interesting discussions, it's obvious
that lots of people have opinions.. which is nice, though I'm not looking to
get into discussions, I'm focusing on building a website.

No it isn't. Not in my beginners classes, nor in PBP. When I'm teaching
newcomers to Perl, I focus my examples entirely on readability and
maintainability.

You've stated that you *don't* expect newbies to know how to read that line.

No. Real people want to solve real world problems in a simple, maintainable
way, not wave around a canapé sized penis.
Another example you can add maybe after some further tweaking:
#!/usr/bin/env perl
use Dancer;
get '/' => sub {
"Hello World!"
};
dance;
$ perl bin/app.pl &
...
$ curl http://localhost:3000/

Ask Damian.
I also agree, it's a speedbump for my reading. KISS etc.
