By default we need to set a full uri in form() function to build a <form> in template, for example:
{{ form('some/great/action/', 'id': 'great_form') }}
{{ form.render('some_input') }}
{{ submit_button('Submit') }}
</form>
I can set a name (for example 'great') for route via RouteInterface->setName() function, but can I use this name in templates?
