I have a cheap validation regex for UUIDs on routes - mostly to distinguish :stuff

my $uuid = qr/[[:xdigit:]]{8}-([[:xdigit:]]{4}-){3}[[:xdigit:]]{12}/;

I use it like so:

$r->get('/comments/:object' => [ object => $uuid ])
  ->to('comments#list_by_item');
  
or, like this:

my $fav = $r->under('/favorites/:object/:id' => [ id => $uuid ])
              ->to('favorites#exist')

when I had it like this:

my $fav = $r->under('/favorites/:object/:id' => [ object => $uuid, id => $uuid ])
              ->to('favorites#exist')

the second param - never the first - ALWAYS was:

[Tue Sep 15 11:37:17 2015] [debug] "9250-"

Ok, maybe I used a reserved name or something - but no, renaming didn't help.

So I suspected I'm simply breaking the URL lengths - but no, not even close. 

Then I thought, ah, I'm an idiot, I just already have the wrong URL!! 

But no, I did not:

curl -X GET -H "Content-Type: application/json" http://localhost:5000/annotations/favorites/$ITEMID/$FAVID

resolves perfectly fine to: 

http://localhost:5000/annotations/favorites/e72cecb5-c457-4b37-9250-c260d3a42731/98ccc1bb-e32f-4970-bee0-a4a4b0357473

(Ignore that it's ugly ;)

Weirdly, it works here - with something other than UUIDs:

my $fol = $r->under('/followers/:user/:follower' => [ user => $user, follower => $user ])
            ->to('followers#exist')

($user being another qr//; thing)

That weird change to "9250-" happens only on using $uuid twice.

Am I overlooking something totally obvious?
