signatures on anonymous subs

[mjb152]

I'm using signatures for my Controllers, and all works well.  I'd like to use them for helpers in my plugins,  but it doesn't appear to work.

use v5.22;

$app->helper(  logme => sub ( $c,$str ) {     $c->app->log->info($str)   });

gives error: Illegal character in prototype for ? : $self

working code

$app->helper(  logme => sub {

            my ($c, $str) = @_;

            $c->app->log->info($str);

 });

am I doing something wrong, or do subroutine signatures not work with anonymous subs under mojo helpers ?

use v5.22;

use experimental 'signatures';
