App::createaccepts a function. A closure is not possibile.
GETqueries where the same parameter appears multiple times, in order to pass a list of values for that parameter.
context.query_params, but as this is a hash map,
varonly gets one value, the last one.
request.path, is there a way to retrieve that as a vector or some kind of collection per parameter?
