No error when port is already taken?

[mnn]

    my Cro::Service $service = Cro::HTTP::Server.new:
            :$host, :$port, :$application;
    $service.start;

doesn't throw when port is already occupied by other application. I didn't find any documentation for Server.start beyond very vague

Instances of Cro::HTTP::Server do the Cro::Service role, and as such have the start and stop methods.
