34691	Add a system check for unmatched URL paths' < / >	Adam Johnson	Amir Karimi	"Currently, unmatched angle brackets are silently ignored:

{{{
    path('<int:question_id/vote/', views.vote, name='vote'),
}}}

This leads to a frustrating debugging experience, where a 404 or `NoReverseMatch` could occur and only the eagle-eyed could spot why. Similar to the `^`/`$` system check added in #28663, I propose a new check in `RoutePattern.check()` for unmatched `<` or `>`. It's rather unlikely those characters are legitimately used in URLs.
