Description

Hi guys,

I'd like to set a requirement on a parameter of my routes, this notation works fine:

#[Route('/{_locale}/teacher/create', name: 'app_teacher_create', requirements: ['_locale' => 'fr|en'])]
public function createTeacher(blah blah blah): Response

As I have to write that requirement in dozens of routes, and later I'll probably want to change the list, I prefer to set it in a configuration file:

# Config/Services.yaml
parameters:
    app.supported_locales: ['en', 'es', 'fr']

Then my controller is modified:

#[Route('/{_locale}/teacher/create', name: 'app_teacher_create', requirements: ['_locale' => '%app.supported_locales%'])]
public function createTeacher(blah blah blah): Response

But unfortunately:

RuntimeException: The container parameter "app.supported_locales", used in the route configuration value "%app.supported_locales%", must be a string or numeric, but it is of type "array".

Well, I could do:

# Config/Services.yaml
parameters:
    app.supported_locales: 'en|es|fr'

But this is kinda strange, in some other place I might prefer to have the array in config file, so that I can browse it item by item.

Support of arrays in route parameters' requirement would seem nice don't you think?
