in reply to Anonymous sub clarification

As LanX said, it's just a parenthesis-less method call to "get". "=>" is often called a "fat comma" in Perl; but more over it's like passing an anonymous hash to the "get" method as implemented by Mojo.
IOW, it's also equivalent to the following where "/" is the hash key and anonymous subroutine is the hash value: 
my $hash_ref = { '/' => sub {...} };
get($hash_ref);

And for that matter, 
my $array_ref = [ '/', sub {...} ];
get($array_ref);

Ultimately, you are associating the subroutine handler for the URL; in this case, "/".

    Hi perlfan,

    I just tested this with Mojolicious::Lite, and I had to dereference the hash/array with get(%$hash_ref); / get(@$array_ref); for it to work.

      Cool, then I was close. I didn't test it and I don't use Mojo, but I think I made my point. Thanks!
